If you’re a Sec 1–5 or O Level student in Singapore, you’ve probably seen ads for the Preply company when you search for online tutors.
Preply looks convenient: many tutors, flexible timing, can learn from overseas teachers. But if your main goal is scoring well in O Levels under the MOE syllabus, you need to ask a very specific question:
“Stuck on a question? See simple explanations that help you understand fast.”
👉 Give it a try and turn confusion into clarity in minutes.

“Is Preply actually better than local Singapore tuition options – including AI tools like Tutorly.sg – for my O Levels?”
This article is written for Secondary / O Level students in Singapore (and parents) who want a clear comparison, not marketing slogans.
We’ll go through:
- How Preply works vs local tuition vs Tutorly.sg
- What matters specifically for O Level success
- A step-by-step tutorial on using Tutorly.sg for daily revision
- An exam strategy guide tailored to O Levels
- Worksheet-style practice (with hard variants) you can try now
- Common mistakes students make when choosing tuition platforms
Throughout, I’ll be very direct about when Preply is useful, and when a Singapore-specific option is simply better.
Preply Company vs Singapore Options: A Straightforward Comparison
Let’s zoom out first. You basically have three categories:
- Preply (international tutoring marketplace)
- Local Singapore tuition (centres, private tutors, school teachers doing tuition)
- Singapore-built AI tutor like Tutorly.sg
1. What Preply Is Good At
Preply is a global tutoring marketplace. You can:
- Filter tutors by language, price, availability
- Learn from overseas teachers
- Book 1-to-1 online lessons
Preply is especially strong for:
- Conversational English
- Foreign languages (e.g. Korean, Japanese, Spanish)
- General maths / general science
If you want to practise spoken English with foreigners or learn a new language, Preply can be quite useful.
2. Where Preply Struggles For Singapore O Levels
For MOE O Level students, there are a few big issues:
-
Not MOE-syllabus focused
Most tutors are not trained in Singapore’s MOE syllabus. They might teach:- “Algebra” but not in the exact style needed for O Level E.Math / A.Math
- “English essay writing” but not with MOE’s Paper 1 requirements
- “Chemistry” but not the specific topics and phrasing used in O Level exams
-
No PSLE / O Level / N Level / A Level alignment
You need:- Structured practice by topic
- Familiarity with TYS-style questions
- Exposure to Singapore exam phrasing (e.g. “hence”, “state and explain”, “comment on”)
Overseas tutors often don’t understand how strict our marking schemes are.
-
Inconsistent quality for exam prep
Some tutors might be amazing, but:- You’ll spend time and money testing different tutors
- They may not know what’s realistic for an Express vs NA vs IP student
- They may not know the weightage of each paper or how to strategise for O Levels
For general learning, Preply is fine. For high-stakes O Levels, it’s usually not the most efficient path.
3. Local Singapore Tuition: Pros and Cons
Pros:
- Tutors know MOE syllabus, exam formats, and common question types
- They use past-year papers from O Levels and top schools
- They understand local context: CCA, school tests, streaming, subject combinations
Cons:
- Fixed timeslots (hard if you have CCA or late remedials)
- Travelling to centres (especially if they’re in Bishan, Bukit Timah, Kovan, etc.)
- Group classes may move too fast or too slow for you
- Private tutors can be expensive $1–$3/hr
4. Where Tutorly.sg Fits In (Very Singapore-Specific)
Tutorly.sg is a 24/7 AI tutor website built specifically for Singapore students, from Primary 1 to JC 2.
Key differences from Preply:
- Aligned to MOE syllabus – including Sec 1–5, N(A), N(T), O Levels, and JC
- Designed for PSLE, O Level, and A Level style questions
- You choose your level and subject, and it responds at that level
- It’s always available – 11pm before a test, 6am before school, doesn’t matter
- Used by thousands of students in Singapore, and has been mentioned on CNA (Channel NewsAsia)
Where it’s strongest for O Levels:
- Step-by-step worked solutions for maths and science questions
- Practice with exam-style questions (including harder variants)
- Quick help when you’re stuck on homework or TYS questions
And importantly: it’s not a mobile app – it’s a website you access through your browser:

Step-by-step tutorial: How To Use Tutorly.sg For O Level Prep (Instead Of Random Preply Lessons)
Instead of booking random Preply lessons hoping the tutor understands O Levels, you can build a daily routine with Tutorly.sg that is tightly aligned with MOE.
“Access more than 1000+ past year papers to practice”
👉 Start a paper today and test yourself like it’s the real exam.

Here’s a practical step-by-step you can follow today.
Step 1: Decide Your Focus Subject (Don’t Try To Fix Everything At Once)
Ask yourself:
- Which subject is dragging your overall L 1 R 5 / EMB 3 down?
- Where do you feel “I study but still get stuck” most often?
Common combos:
- E.Math + A.Math
- Pure Chemistry
- Pure Physics
- Combined Science (Chem/Phy or Chem/Bio)
- O Level English Paper 2 (Comprehension)
Pick 1–2 subjects for the first two weeks. Once you see improvement, then expand.
Step 2: Go To Tutorly.sg And Set Up Your Level & Subject
Visit:
👉 https://tutorly.sg/app
You’ll:
- Select your level
- Select your subject (e.g. A.Math, Pure Chem, English)
This is where Tutorly.sg is very different from Preply:
- You don’t need to explain “I’m doing O Level A.Math in Singapore” every time
- It already expects MOE-style questions and syllabus
Step 3: Use Your School Materials As The Base
Instead of random internet questions, use:
- Your school worksheets
- Your class tests
- TYS questions
- Top school papers (if your teacher gives them)
Whenever you’re stuck on a question:
- Type the full question into Tutorly.sg
- If it’s maths/science, type the exact numbers and wording
- If it’s English comprehension or summary, paste the passage/question (or key parts)
Tutorly will:
- Check your final answer (not every working step)
- Then show you a step-by-step solution so you can see how to get from question to answer
This is something many Preply tutors do manually (and you pay per hour). With Tutorly, you can do it question by question, anytime.
Step 4: Turn Every Mistake Into A Mini-Lesson
When you get a question wrong:
-
Read the full solution from Tutorly.sg slowly
-
Ask it follow-up questions like:
- “Why did you choose this formula here?”
- “Can you show another method?”
- “What are similar questions that students often get wrong?”
-
Then ask it to generate 3–5 similar questions for you to try immediately.
This is how you turn one mistake into solid mastery of a concept.
On Preply, if you do this, you’re burning time during a live session. On Tutorly, you can take your time without worrying about hourly cost.
Step 5: Build A Simple Weekly Schedule (Realistic For CCA Kids)
Here’s a realistic plan for a Sec 3–4 student with CCA:
Mon, Wed, Fri (30–40 mins each)
- 10 mins: Revise one concept (e.g. A.Math: Partial Fractions, Chem: Mole concept)
- 20–25 mins: Do 4–6 questions from school worksheets or TYS
- Last 5 mins: Use Tutorly.sg to check and understand mistakes
Sat or Sun (45–60 mins)
- 20–30 mins: Full practice section
- 20–30 mins: Review with Tutorly.sg, and ask it to generate 2–3 harder variants of the questions you struggled with
This routine is very hard to maintain with a Preply tutor (scheduling, time zones, cost), but very doable with a 24/7 AI tutor website.
Exam Strategy Guide: O Level Tactics You Won’t Get From Generic Overseas Tutors
Let’s be very specific now. Here’s how you can use local-style strategies + Tutorly.sg to outperform a generic Preply-based approach.
1. O Level E.Math: Focus On Speed + Zero-Careless-Mistakes
Common issue: Students can do the questions… but too slowly and with careless errors.
Strategy:
- Target: Finish Paper 1 with at least 10 minutes to check
- Train with timed sets of 5–10 questions
Using Tutorly.sg:
- Take 5 E.Math questions (from school or TYS)
- Set a timer
- Do them without checking answers
- After time’s up, use Tutorly.sg to:
- Check your answers
- See full solutions
- Identify where you wasted time or made careless slips
Ask Tutorly:
- “Give me 5 more questions similar to Q 3 but slightly harder, O Level standard.”
Repeat weekly. This builds exam speed – something generic Preply tutors often don’t train systematically for O Level format.
2. O Level A.Math: Drill Key High-Yield Topics
Big scoring topics:
- Indices & Surds
- Quadratic equations & inequalities
- Trigonometry
- Coordinate geometry
- Differentiation & integration
Strategy: Topic-by-topic mastery
- Pick one topic per week (e.g. Differentiation: product rule, quotient rule, chain rule)
- Do 8–10 questions from that topic
- For any question you can’t do in 3 minutes, send it to Tutorly.sg
Ask:
- “Show me the step-by-step solution for this Sec 4 O Level A.Math question.”
- “Explain why you used the quotient rule and not the product rule here.”
- “Generate 3 harder O Level-style questions on differentiation like this.”
This targeted drilling on Singapore-style questions is something many Preply tutors won’t know how to structure, because they’re not familiar with O Level exam weightage.
3. O Level Pure Chemistry: Learn To Answer In Marking-Scheme Language
In Singapore, Chem isn’t just about “knowing the concept”. You must phrase answers the way marking schemes expect.
Example:
- Not enough: “The reaction is exothermic.”
- Better: “The reaction is exothermic because heat is released to the surroundings, causing the temperature of the solution to increase.”
Using Tutorly.sg:
-
Type in a structured question you got wrong, e.g.
“Explain why the temperature of the solution increased during the reaction.” -
First, try to answer it yourself.
-
Then ask Tutorly.sg:
- “Show me an O Level Pure Chemistry model answer for this question.”
- “Explain which keywords are important to get full marks.”
This is where Preply tutors who are not from Singapore often fall short – they might give you a scientifically correct answer, but not in the exact phrasing MOE markers look for.
4. O Level English: Comprehension & Summary
Many overseas English tutors (including on Preply) focus on:
- Grammar
- Conversation
- General essay writing
But O Level English is very specific:
- Paper 1: Situational writing + continuous writing
- Paper 2: Comprehension, language use, summary
Using Tutorly.sg:
- Paste a comprehension passage and question
- Attempt answers first
- Then ask:
- “Show me how an O Level marker would answer this question.”
- “Explain why this answer gets 1 mark and not 2.”
- “Show me a breakdown of the summary points from this passage.”
You get exam-focused feedback instead of vague “your English is good” comments.
Worksheet Practice: Try These Questions (With Hard Variants)
Let’s do some actual practice, the way you’d do on Tutorly.sg. I’ll give you:
- A standard question
- A harder variant
- A short hint on how Tutorly would walk you through it
A. E.Math Algebra – Standard vs Harder
Q 1 (Standard):
Solve for :
Try it yourself first.
On Tutorly.sg, you’d type the full question and it would show:
- Step 1: Bring all terms to one side
- Step 2: Bring constants to the other side
- Step 3: Simplify and solve
Q 1 (Harder Variant – Still E.Math Level):
Solve for :
Key idea:
- Find common denominator
- Combine fractions
- Solve linear equation
On Tutorly.sg, you could ask:
- “Show me step-by-step how to solve this, explaining each algebra move.”
B. A.Math – Trigonometry Identity
Q 2 (Standard):
Prove the identity:
Harder Variant (O Level A.Math style):
Prove:
Hints Tutorly.sg would give:
- Express everything in and
- Use and
- Simplify one side until it matches the other
You can type:
“I tried to prove this but got stuck at this step: [paste your working]. Show me the remaining steps and explain where I went wrong.”
(Remember: Tutorly checks your final answer, then gives a full correct solution. It doesn’t trace every line of your working, but you can paste parts to ask about specific mistakes.)
C. Pure Chemistry – Mole Concept
Q 3 (Standard):
of oxygen gas, , is used in a reaction.
Calculate the number of moles of oxygen molecules used.
You’d expect Tutorly.sg to:
- Show the formula:
- Oxygen gas has molar mass
- Then calculate moles step-by-step
Q 3 (Harder Variant – Application):
Magnesium reacts with oxygen to form magnesium oxide:
of magnesium metal is completely burned in oxygen.
- Calculate the number of moles of magnesium used.
- Using the equation, find the number of moles of magnesium oxide formed.
- Calculate the mass of magnesium oxide formed.
Tutorly.sg would walk you through:
- Step 1: Moles of Mg =
- Step 2: Use mole ratio from balanced equation
- Step 3: Convert moles of MgO to mass
You can then ask:
“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.
![Secondary Science topics you can practise on Tutorly.sg]
“Give me 3 more O Level Pure Chemistry questions on mole concept and mass, slightly harder than this.”
D. O Level English – Summary Practice
Q 4 (Standard):
You’re given a passage about the impact of social media on teenagers’ sleep. The summary question says:
“In no more than 80 words, summarise the reasons why social media affects teenagers’ sleep and the consequences of this lack of sleep.”
On Tutorly.sg, you can:
- Paste the relevant paragraphs
- Attempt your own summary
- Then ask:
- “Show me an O Level-standard summary for this question.”
- “Highlight the key points that must be included to get full marks.”
Harder Variant:
Ask Tutorly.sg:
“Generate a short passage and an O Level style summary question. Then show me a model summary answer.”
Then:
- Hide the model answer
- Try writing your own first
- Reveal Tutorly’s model answer and compare
This kind of self-training loop is very hard to do with Preply unless you have a very exam-focused tutor who understands O Level English specifically.
Common Mistakes: Preply vs Local Tuition vs Tutorly.sg
When students and parents compare Preply with local options, they often fall into a few traps.
Mistake 1: Treating “Any English Tutor” As Equal To “O Level English Specialist”
Many Preply tutors are great at general English, but:
- They haven’t seen MOE O Level English papers
- They don’t know Paper 1 / Paper 2 structure
- They don’t know how marks are allocated for summary, comprehension, situational writing
For O Levels, you need someone (or something, like Tutorly.sg) that understands:
- The exact exam format
- The marking scheme style
- The typical question types and common traps
Mistake 2: Paying Hourly For Things You Could Practise Daily On Your Own
Some students use Preply for:
- Going through homework
- Doing step-by-step maths questions
- Practising grammar worksheets
These are things you can do every day with Tutorly.sg, without worrying about hourly fees.
A more efficient pattern:
- Use Tutorly.sg daily for questions, practice, and explanations
- If you still want a human tutor, use them for higher-level strategy:
- Planning revision schedule
- Explaining big-picture concepts
- Checking your essays in detail
Mistake 3: Ignoring The Syllabus Difference
Preply tutors may be teaching:
- IGCSE
- IB
- American curriculum
- UK GCSE
These are not the same as:
- Singapore O Level
- N(A), N(T) streams
- Sec 1–2 lower secondary syllabus
Even topics that sound similar (e.g. “Quadratic equations”) can:
- Have different depth
- Appear in different formats
- Have different common question types
Tutorly.sg is built specifically for MOE, so it doesn’t mix random international styles into your practice.
Mistake 4: Only Starting Help In Sec 4
Many students delay getting help until:
- Sec 4 mid-year or prelims
- When they fail a few tests in a row
By then, you’re trying to fix Sec 3 + Sec 4 content at the same time.
A better plan:
- Start using Tutorly.sg from Sec 2–3 for:
- Clarifying confusing topics immediately
- Practising exam-style questions early
- Building strong algebra/chem foundations
Then by Sec 4, you’re polishing, not firefighting.
When Preply Might Still Be Useful (And When Tutorly.sg Is Clearly Better)
To be fair, there are situations where Preply can still be a good choice:
Preply is useful if you:
- Want to learn a foreign language not taught in school
- Want to practise spoken English with foreigners
- Are not focused on MOE exams, but on general improvement
Tutorly.sg and local Singapore tuition are better if you:
- Care about O Level results
- Need help with E.Math, A.Math, Pure/Combined Science, or O Level English
- Want practice and explanations that match MOE style and marking schemes
And unlike Preply:
- Tutorly.sg is available 24/7
- It’s a website, not an app – just go to https://tutorly.sg/app
- It’s already used by thousands of students in Singapore and has been featured on CNA
Final Thoughts: Choose The Tool That Matches Your Exam, Not Just Your Budget
Preply is not “bad”. It’s just not built for Singapore MOE exams.
If your main goal is:
- Getting from C/B to A in E.Math or A.Math
- Moving from borderline pass to solid B/A in Pure Chem or Physics
- Pushing your O Level English grade up for L 1 R 5
Then you need something that:
- Knows the MOE syllabus
- Speaks the same exam language as your papers
- Lets you practise daily without worrying about hourly cost
That’s exactly what Tutorly.sg is designed for.
