Step-by-step tutorial: Using Preply effectively as a Singapore secondary student

Preply is basically a marketplace of tutors from all over the world. Some are great, some are… not so aligned to MOE.

If you just click the first “cheap” tutor, you’ll probably end up going through generic content that doesn’t match your exam style.

Here’s a realistic, Singapore-focused way to use Preply step by step.

1. Start with your real goal (be specific)

Don’t just say “I want to improve Maths”.

For O Level / N Level / IP, you want something like:

• “I’m Sec 3 Express, aiming for A 2 in A-Math next year.”
• “I’m Sec 4 NA, retaking O Level English, weak in situational writing.”
• “I’m Sec 2, struggling with algebra and algebraic fractions.”

Write this down before you even open Preply.
It will guide everything you do next.

Then, be even more concrete:

• Which topics? (e.g. Trigonometry, Algebra, Mole concept, Summary writing)
• Which exam? $Sec 2 EOY / O Level / School prelims$
• What’s your current grade?

You’ll use this when talking to tutors and when setting up your AI practice later on Tutorly.sg.

---

2. Filter tutors with Singapore and exam keywords

When you search on Preply, don’t just choose “Maths” or “English”.

Use keywords in the search or in your message like:

• “O Level Additional Mathematics”
• “O Level Pure Chemistry (Singapore)”
• “Secondary 3 Express Math (MOE syllabus)”
• “O Level English Paper 1 & 2 (Singapore)”

Then, when viewing tutor profiles, look for:

• Mentions of “O Level”, “GCSE”, “IGCSE” – closer, but not always the same
• Best: “Singapore” / “MOE” / “PSLE / O Level / A Level” in their description
• Experience teaching Singapore students (if they mention “students from Singapore” or “MOE syllabus”, that’s a good sign)

If none of this appears, assume they might not know our exam style, even if they’re good at the subject in general.

---

3. Send a clear first message (so you don’t waste trial lessons)

Before booking, send a short, focused message like this:

Hi, I’m a Sec 3 Express student in Singapore.
I’m taking O Level A-Math next year.

I’m weak in:
– Algebraic manipulation (especially factorisation and partial fractions)
– Trigonometry (identities and solving equations)

I want help with:
– MOE / O Level-style questions
– Timed practice and explaining exam tricks

Have you taught Singapore O Level students before?
Can you do lessons based on the O Level A-Math syllabus?

This does 3 things:

1. Tests if they actually read your message
2. Checks their familiarity with MOE/O Level
3. Forces them to say what they can realistically do

If they reply with something generic like “Yes, I can help you with math, don’t worry” and never mention O Levels or Singapore, that’s a red flag.

---

4. Use the first lesson as a trial exam session

Don’t let the first lesson become a “get to know you” chat for 45 minutes.

Before the lesson, prepare:

• 3–5 recent school questions you got wrong
• 1 harder question from your school worksheet / Ten-Year-Series
• Your latest test paper (if possible)

During the lesson, tell the tutor:

• “Can we go through these questions like an exam coach?”
• “Please show me the shortest, clearest method that would score full marks in O Level marking scheme.”

Observe:

• Do they use the same notation and methods as your school teacher?
• Do they break down steps in a way you can follow?
• Do they give exam tips (e.g. where marks are usually lost, how to structure answers)?

If they can’t handle your actual school questions, they’re probably not the right fit for O Level-style work.

---

5. After the lesson: lock in a plan (don’t drift)

If the tutor is good, you should end the first lesson with a simple plan:

Example for O Level A-Math:

• Weekly 1-hour lesson
• Focus by topic:
  • Week 1–2: Algebra (factorisation, inequalities, surds)
  • Week 3–4: Trigonometry (identities, equations)
• Every lesson:
  • 30 min: explaining concepts + 2–3 medium questions
  • 20 min: 1–2 hard questions $prelim / TYS level$
  • 10 min: exam technique + summary of mistakes

Then, in between lessons, you need practice.
This is where most students fail: they only “learn” during tuition, but don’t drill enough alone.

This is exactly where Tutorly.sg fits in.

---

6. Fill the gaps with 24/7 Singapore-based AI practice (Tutorly.sg)

Preply tutors are human, so:

• They cost per hour
• They can’t be with you at 11.30pm the night before your math test
• They may not always know MOE marking styles in detail

Tutorly.sg is different:

• It’s built specifically for Singapore students, from Primary 1 to JC 2
• It’s aligned to the MOE syllabus (including O Levels and IP)
• It runs in your browser – no download needed, and it’s not a mobile app
• It has already been used by thousands of students in Singapore and has even been mentioned on Channel NewsAsia (CNA)

How to combine both:

• Use Preply for:
  • Concept explanation when you’re really stuck
  • Verbal guidance and live Q&A
• Use Tutorly.sg for:
  • Daily question drilling
  • Checking answers instantly
  • Getting step-by-step solutions when you’re alone

You can open https://tutorly.sg/app anytime and:

• Paste a question from your school worksheet
• Get the final answer checked
• Then see a full step-by-step solution, written for your level and subject

This way, you’re not waiting one whole week for the next Preply lesson just to find out you misunderstood a topic.

Exam strategy guide: Turning Preply + AI into O Level results

Once you’ve set up Preply and Tutorly.sg, you need a strategy that actually improves your grades.

“Access more than 1000+ past year papers to practice”
👉 Start a paper today and test yourself like it’s the real exam.

Here’s how to structure your weeks for O Level / Sec 3–4.

1. Weekly structure (Math / Science example)

If you have 1 Preply lesson per week for A-Math:

• Day of lesson (e.g. Sunday):

  • 1 hour Preply – focus on 1–2 topics
  • After lesson: spend 20–30 min on Tutorly.sg doing 5–10 questions on the same topics

• Mid-week (e.g. Wed/Thu):

  • 30–40 min self-practice
  • Use school worksheet or Ten-Year-Series
  • Check answers and solutions with Tutorly.sg

This rhythm means:

• Your tutor introduces and clarifies concepts
• You drill them on your own
• You use AI to correct and learn from mistakes immediately

Instead of just “hoping” you remember by the next lesson.

---

2. Use Preply for exam-style thinking, not just content

For O Levels, knowing content is not enough. You need:

• Speed
• Accuracy under pressure
• Familiarity with question patterns

Ask your Preply tutor to:

• Go through full questions, not just mini examples
• Time you for certain questions $e.g. 5 minutes for a 5-mark algebra question$
• Explain why exam setters like to combine topics $e.g. Trigo + Coordinate Geometry$

Example for A-Math:

“Can we do 2 full O Level-style questions each lesson, and you watch how I think, then point out where I’m wasting time or making typical errors?”

This turns tuition into exam training, not just “extra school”.

---

3. Use Tutorly.sg to simulate exam conditions

Before a school test or prelim:

1. Pick a topic (e.g. Quadratic Equations)
2. Set a timer for 25–30 minutes
3. Attempt a set of questions (from your worksheet or past papers) without checking
4. After that block, open Tutorly.sg:
   • Check each final answer
   • For any wrong ones, ask for a full step-by-step explanation
   • Compare your method with the AI’s method

Over time, you’ll see patterns:

• Maybe you always mess up signs in algebra
• Or you always forget to convert units in Physics
• Or you lose marks in English for not answering the question directly

You can then bring these patterns back to your Preply tutor and say:

“I keep losing marks in these 2 areas, can we drill them next lesson?”

This makes your paid lessons much more efficient.

---

4. Subject-specific strategies

Math (E-Math / A-Math)

With Preply:

• Focus on topics you’re weakest in, not everything
• Ask the tutor to show you common O Level question types for each topic
• Ask them to mark a short “mock section” you do during class

With Tutorly.sg:

• After each topic, do 5–10 mixed questions
• When you get a question wrong, don’t just memorise the steps – ask the AI to:
  • Explain why that method works
  • Show alternative methods if possible

Science (Pure / Combined)

With Preply:

• Use it to clarify concepts that are hard to visualise (e.g. Electrolysis, Organic Chem, Lenses)
• Get them to quiz you orally on definitions and key terms

With Tutorly.sg:

• Practise structured questions (especially “Explain”, “Describe”, “Account for”)
• Paste your answers and compare with the AI’s model answer
• Pay attention to scientific keywords and phrasing used

English

Preply can be very useful here, especially with tutors who are strong in writing and comprehension.

With Preply:

• Do live practice for:
  • Situational writing (letters, emails, proposals)
  • Continuous writing (narrative, discursive)
• Ask the tutor to “mark” your writing like an O Level marker

With Tutorly.sg:

• Draft your essay or summary, then:
  • Ask for feedback on clarity and structure
  • Ask for alternative topic sentences or better phrases
• Practise comprehension by pasting passages and your answers, then compare with AI explanations

---

Worksheet practice: Sample questions (with hard variants)

To really see how Preply and Tutorly.sg can work together, let’s walk through some practice styles you can use.

Below are sample question types you should be drilling regularly.

You can try similar questions, then check and learn from them using Tutorly.sg.

---

1. E-Math: Algebra (medium)

Question 1 (Medium)
Simplify fully:
$\frac{3 x^2 - 12}{6 x - 24}$

How to use this:

• Try it on your own first
• Then key your final answer into Tutorly.sg to check
• If wrong, read the step-by-step solution and note the factorisation method

---

2. A-Math: Trigonometry identities (harder)

Question 2 (Hard)
Prove the identity:
$\frac{1 - \cos x}{\sin x} = \frac{\sin x}{1 + \cos x}$

This is the kind of question many Sec 3/4 A-Math students struggle with.

How to approach:

1. Start with LHS: $\dfrac{1 - \cos x}{\sin x}$
2. Multiply numerator and denominator by $(1 + \cos x)$
3. Use $1 - \cos^2 x = \sin^2 x$

If you get stuck:

• Ask your Preply tutor to walk through similar identity proofs during your lesson
• After that, practise 3–5 more identity questions on Tutorly.sg until the pattern feels natural

---

3. Pure Chemistry: Mole concept (medium–hard)

Question 3 (Medium–Hard)
A sample of magnesium reacts completely with excess hydrochloric acid to produce 4.48 dm$^3$ of hydrogen gas at room temperature and pressure.

(a) Write a balanced chemical equation for the reaction.
(b) Calculate the number of moles of hydrogen gas produced.
(c) Hence, find the mass of magnesium that reacted.
(Relative atomic mass, Mg = 24.0; molar gas volume at r.t.p. = 24.0 dm$^3$ mol$^{-1}$)

Again, this is very typical O Level style.

Use Tutorly.sg to:

• Check your final answers
• See a full solution if you’re unsure how to link moles of gas to mass of solid

Then, in your next Preply lesson, ask your tutor to:

• Give you more questions that mix mole concept with limiting reagents or concentration
• Test you verbally on each step so you don’t just copy

---

4. English: Situational writing (hard variant)

Question 4 (Hard)
Your school has noticed an increase in littering around the canteen and school compound.
As the President of the Student Council, write a formal email to the Principal proposing three practical measures the school can implement to reduce littering and encourage students to take ownership of their environment.

Your email should:

• Be between 250–350 words
• Use a formal tone
• Include clear justifications for each measure

How to use Preply + Tutorly.sg:

• Draft your email on your own
• Paste it into Tutorly.sg and ask for:
  • Feedback on structure (introduction, body, conclusion)
  • Suggestions to make your justifications stronger
• Then, share the improved version with your Preply tutor and ask them to:
  • Mark it using O Level criteria (Content, Language, Organisation)
  • Point out specific grammar or phrasing weaknesses you keep repeating

---

5. Hard exam-style variants (Math)

You should always include some “prelim-level” or harder variants in your practice.

Question 5 (Hard A-Math)
Solve the equation for $0^\circ \le x \le 360^\circ$:
$2\sin x \cos x = \cos x$

Many students forget to consider different cases, e.g. $\cos x = 0$ or dividing both sides (which may lose solutions).

Try it, then:

• Check your final list of $x$ values using Tutorly.sg
• Study the AI’s explanation carefully to see how it handles the $\cos x = 0$ case

In your next Preply lesson, you can say:

“I always get confused about when I can divide by a trig term. Can we go through 3–4 questions like this?”

“Doing Secondary Science? Pick a topic and practise like it’s a real exam — with clear answers right after.”
👉 Try Tutorly now and start a Science topic in seconds.

This tight loop $self-practice → AI explanation → human clarification$ is extremely powerful.

Common mistakes when using Preply (and how to avoid them)

Many secondary students in Singapore use Preply in ways that don’t actually help their grades much.

Here are the most common pitfalls – plus what to do instead.

---

Mistake 1: Choosing tutors based only on price

Cheaper doesn’t always mean worse, but if you only filter by lowest price, you’ll likely get:

• Tutors unfamiliar with MOE syllabi
• Generic teaching that doesn’t match O Level question styles
• Lots of time spent on content you already know

Fix:
Prioritise:

• Experience with “O Level”, “Singapore”, “MOE”
• Clear communication in English
• Ability to explain why answers work, not just the final answer

Use your first message to test this before you pay for a full package.

---

Mistake 2: Treating Preply as a replacement for practice

Many students sit through 1–2 hours of online tutoring each week, feel “productive”, but barely do any questions on their own.

End result:
Their conceptual understanding improves slightly, but exam performance doesn’t.

Fix:
Use this simple rule:

For every 1 hour of Preply, aim for at least 2 hours of self-practice.

You don’t need to suffer alone during those 2 hours. Use Tutorly.sg to:

• Check answers
• Learn from detailed step-by-step solutions
• Clarify concepts in your own time

---

Mistake 3: Not aligning lessons to school / O Level syllabus

Some tutors are used to:

• US-style curricula
• UK GCSE / A-Level
• IB

These can be similar but not identical to O Level.

Examples of misalignment:

• Different topics (e.g. set theory, statistics emphasis, proof styles)
• Different depth $e.g. certain A-Math topics$
• Different exam formats

Fix:

• Send your syllabus or topic list (from your textbook or school notes) to your tutor
• Say clearly: “I’m preparing for O Level [subject], can we follow this list of topics?”
• Regularly bring school test questions to lessons – if they struggle with these, you need to reconsider

---

Mistake 4: Passive learning during lessons

If you spend the entire Preply lesson just listening and copying notes, you’re not preparing for exam pressure.

Fix:

• During lessons, try to answer questions live before the tutor shows the solution
• Ask them to give you short timed tasks $e.g. “Do this 4-mark question in 4 minutes”$
• Ask “why” and “how” questions:
  • “Why is this step necessary?”
  • “How would this be marked in an O Level paper?”

This builds active problem-solving skills, not just memorisation.

---

Mistake 5: Ignoring your own error patterns

If you keep making the same algebra mistake or the same type of comprehension error, but no one is tracking it, you’ll carry it into the O Levels.

Fix:

1. After each practice session with Tutorly.sg, quickly note:
   • Topic
   • Type of mistake (careless, concept, misreading, time pressure)
2. Share this list with your Preply tutor and say:
   • “These are my top 3 recurring mistakes. Can we focus on them this month?”

This is far more effective than just saying “I’m weak in Math”.

---

Final thoughts: So… can Preply help with O Levels?

Yes – if you:

• Choose tutors who understand the Singapore / MOE context
• Use lessons for deep explanation and exam strategy
• Combine it with regular, focused practice

But Preply alone is not enough.

You need something that:

• Is available anytime (not just during scheduled lessons)
• Understands the MOE syllabus and local exam styles
• Gives instant feedback and full worked solutions

That’s exactly what Tutorly.sg is built for.

---

Try this tonight: A simple 3-step plan

If you want a concrete action plan you can start today:

1. Shortlist 1–2 Preply tutors

   • Message them with your level, subject, and that you’re preparing for O Levels in Singapore
   • Ask directly if they’ve taught Singapore students before

2. Do one focused trial lesson

   • Bring real school questions
   • Ask for exam-style explanations and tips

3. Set up your 24/7 practice base at Tutorly.sg

   • Go to https://tutorly.sg/app in your browser
   • Start by pasting 3–5 questions from your latest homework or test
   • Check your answers, study the solutions, and note down any patterns in your mistakes

Over the next few weeks, let your human tutor and AI tutor work together:

• Human (Preply): big picture, explanation, live feedback
• AI (Tutorly.sg): endless practice, instant solutions, MOE-aligned guidance

If you’re serious about improving your Sec 1–4 / 5 or O Level results, this combination is one of the most efficient ways to use your time and your parents’ money wisely.
