Step-by-step tutorial: How to register as a tutor on Preply from Singapore
Let’s go straight to what you probably searched for: the Preply tutor registration process.
Before anything:
Preply is a global tutoring marketplace. Students from all over the world can book lessons with you. It’s not MOE-specific, and it’s not focused on O-Level syllabuses. That’s important to remember.
1. Check if Preply is suitable for you
Before you register, ask yourself:
- Are you at least 18?
- Preply generally expects tutors to be adults. If you’re under 18, you may not be able to register, or you may need to wait. Always check their latest terms.
- Do you have a strong subject you can teach confidently?
- For example:
- English (conversation, writing)
- Math (basic, algebra, geometry)
- Science (general, physics, chemistry)
- Languages (Chinese, Malay, Tamil, or others)
- For example:
- Are you ready to communicate in English with international students?
- Most profiles and lessons are in English.
If you’re still in Secondary school, be honest: your O-Level results and your own revision must be your top priority. Don’t sacrifice your grades just to earn a bit more.
2. Go to Preply and start the tutor sign-up
- Open your browser and go to the Preply website.
- Look for something like “Become a tutor” or “Register as a tutor” (usually at the top or bottom of the homepage).
- Click it and choose Sign up as a tutor.
You’ll usually need to:
- Create an account
- Select which subject(s) you want to teach
Tip as a Singapore student:
If you’re strong in O-Level content, you can position yourself as:
- “Math tutor for lower secondary / basic algebra”
- “Conversational English tutor”
- “Beginner Chemistry tutor”
But avoid overselling. If you’re still doing your own O Levels, don’t claim to be an “expert exam coach”.
3. Complete your tutor profile
Preply will ask you to fill in a profile. This is where many students get stuck or feel shy.
You’ll typically need to provide:
- Name
- Profile photo
- Use a clear, friendly headshot.
- No school uniform if you want to keep your school private. A simple T-shirt is fine.
- Short description / bio
- Who you are
- What you teach
- How you teach
Example bio :
“Hi, I’m a Secondary 4 student in Singapore, currently taking O-Level Pure Math and Pure Chemistry. I help lower secondary students and international learners with basic algebra, fractions, and problem-solving. My style is patient and step-by-step, focusing on building confidence and understanding, not just memorising formulas.”
Be honest about your level. Some students actually appreciate learning from someone closer to their age.
4. Set your availability and hourly rate
You’ll need to:
- Choose time slots you can teach
- Set an hourly rate
As a student tutor:
- Start with a lower rate to get your first few students and reviews .
- Make sure your time slots don’t clash with:
- School hours
- CCA
- Tuition
- Your own study time for O Levels
A simple rule:
On school days, try to keep max 1 tutoring hour in the evening, and only if your homework is under control. Weekends can be slightly heavier, but don’t overbook.
5. Record your intro video (if required)
Preply often encourages or requires a short intro video. This is where many Singapore students feel paiseh, but it’s not that bad.
Basic structure :
- Greet: “Hi, I’m [Name] from Singapore.”
- Subject: “I teach [subject(s)] at [level].”
- Approach: “My lessons are [interactive / step-by-step / patient].”
- Call to action: “Book a trial lesson with me so we can discuss your goals.”
Example script:
“Hi, I’m Sarah from Singapore. I’m currently in Secondary 4, and I teach lower secondary Math and basic Algebra. In my lessons, I break down each problem into clear steps and give you similar practice questions so you really understand the method. If you’d like to improve your math foundations, book a trial lesson with me and we’ll go through your weaknesses together.”
Speak slowly, clearly, and smile. You don’t need special equipment; your laptop webcam is enough.
6. Submit documents (if requested)
Preply may ask for:
- ID verification (passport, NRIC, or other ID)
- Qualifications (certificates, transcripts, etc.)
As a Secondary student, you might not have many formal certificates yet. That’s okay, but be prepared that:
- Some students may prefer tutors with degrees or teaching certificates.
- You might mostly attract:
- Younger students
- Students who want conversation practice
- Students on a budget
Always follow Preply’s rules and never send your NRIC or bank details outside the official platform.
7. Wait for approval and respond quickly
Once you submit:
- Preply may review your profile.
- When it’s approved, you can start receiving messages or booking requests.
To make a good impression:
- Reply quickly (within a few hours if possible).
- Be polite and clear about:
- What you can help with
- Your available times
- Your expectations (homework, materials, etc.)
Exam strategy guide: Balancing Preply tutoring and O-Level preparation
Now the important part: how to avoid destroying your own results while you register as a tutor.
“Access more than 1000+ past year papers to practice”
👉 Start a paper today and test yourself like it’s the real exam.
Your O-Level grades affect:
- JC / Poly admission
- Scholarships
- Future opportunities
Preply income is nice, but it’s not worth sacrificing your future options. So here’s a realistic exam strategy guide for Secondary / O-Level students in Singapore.
1. Fix your non-negotiable study blocks
Before you even open Preply:
-
List your core subjects:
- English
- Mother Tongue
- E-Math
- A-Math (if you take it)
- Pure Sciences / Combined Science
- Humanities
-
For each subject, mark:
- Weak
- Average
- Strong
-
Create non-negotiable study blocks each week:
- Weak subjects: at least 3 focused sessions/week
- Average subjects: 2 sessions/week
- Strong subjects: 1–2 shorter sessions/week
Block these on your calendar before adding any tutoring slots. Treat them like tuition you’ve already paid for.
2. Use teaching to strengthen your own basics (smartly)
Teaching can actually help your own understanding if you do it right:
-
If you teach Lower Sec Math, it reinforces:
- Algebra
- Fractions
- Linear equations
- Basic geometry
-
If you teach basic English, it reinforces:
- Grammar
- Sentence structure
- Vocabulary
But don’t waste time teaching topics that are totally unrelated to your exams when you’re already overloaded.
Example:
If you’re taking O-Level Pure Chemistry, teaching “Primary School English conversation” may not help your own studies much. You might want at least one subject you teach that’s related to your own exam content.
3. Plan around MOE exam periods
In Singapore, typical crunch periods:
- Mid-year exams (around May)
- Prelims (Aug–Sep)
- O Levels (Oct–Nov)
During these periods, you should:
- Reduce your Preply availability
- Inform your regular students early:
- “I have national exams coming up in [month], so I’ll temporarily reduce my slots. After my exams, I can increase them again.”
Your long-term students will usually understand. And if they don’t, that’s still better than failing your own papers.
4. Use Tutorly.sg as your “hidden support”
If you’re teaching others, you need to stay sharp yourself. This is where Tutorly.sg is honestly very useful for Secondary and O-Level students.
Here’s how you can use it:
- When you get stuck on your own A-Math or Pure Chem questions, go to:
https://tutorly.sg/app - Select your level and subject (e.g. Additional Mathematics).
- Paste the question and ask for:
- A step-by-step solution
- A similar practice question with answer
Tutorly:
- Checks the final answer and then shows you how to get there step by step.
- Is aligned to the MOE syllabus, unlike many overseas resources.
- Is available 24/7, so you don’t have to wait for your school teacher or human tutor to reply.
Since thousands of Singapore students are already using Tutorly.sg for PSLE, N-Level, O-Level and A-Level prep, you’re not experimenting with something untested.

Worksheet practice: Build exam-style questions (including hard variants)
Whether you’re:
- Preparing for your own O Levels, or
- Planning lessons for your future Preply students,
you need good practice questions. Let’s create a mini-worksheet set with:
- Basic questions
- Harder variants
I’ll show you how to think about each level, and how you can use Tutorly.sg to generate more practice around them.
Topic 1: Algebra (Secondary / O-Level E-Math)
Q 1 (Basic) – Simplifying expressions
Simplify:
Answer (sketch):
Combine like terms:
So, .
Q 2 (Exam-level) – Solving linear equation
Solve for :
Answer (sketch):
Expand:
So:
8 x - 17 = 3 x + 7$$ Bring variables to one side: $$8 x - 3 x = 7 + 17 \\ 5 x = 24 \\ x = \frac{24}{5}$$ --- #### Q 3 (Hard variant) – Algebraic fractions Solve: $$\frac{3}{x-1} - \frac{2}{x+2} = \frac{5}{x^2 + x - 2}$$ Note: $x^2 + x - 2 = (x+2)(x-1)$. **Answer (sketch):** Left-hand side with common denominator $(x-1)(x+2)$: $$\frac{3(x+2) - 2(x-1)}{(x-1)(x+2)} = \frac{3 x + 6 - 2 x + 2}{(x-1)(x+2)} = \frac{x + 8}{(x-1)(x+2)}$$ Equation becomes: $$\frac{x + 8}{(x-1)(x+2)} = \frac{5}{(x-1)(x+2)}$$ So: $$x + 8 = 5 \\ x = -3$$ Check that $x \neq 1, -2$ (to avoid zero denominator). $x = -3$ is valid. --- If you want more questions like this (but with different numbers), you can ask Tutorly: > “Give me 5 O-Level style algebraic fraction equations similar to this one but with different values, and provide full worked solutions.” Use: [https://tutorly.sg/app](https://tutorly.sg/app) --- ### Topic 2: Quadratic Equations (O-Level E-Math) #### Q 4 (Basic) – Factorisation Factorise: $$x^2 - 5 x + 6$$ **Answer (sketch):** Find numbers that multiply to $6$ and add to $-5$: $-2$ and $-3$. So: $$x^2 - 5 x + 6 = (x - 2)(x - 3)$$ --- #### Q 5 (Exam-level) – Solving by factorisation Solve: $$2 x^2 - 7 x + 3 = 0$$ **Answer (sketch):** We want $(2 x - 1)(x - 3) = 0$: Check: $$(2 x - 1)(x - 3) = 2 x^2 - 6 x - x + 3 = 2 x^2 - 7 x + 3$$ So: $$2 x - 1 = 0 \Rightarrow x = \frac{1}{2} \\ x - 3 = 0 \Rightarrow x = 3$$ --- #### Q 6 (Hard variant) – Word problem A rectangle has a length of $(x + 3)$ cm and a width of $(x - 1)$ cm. Its area is $54 \text{ cm}^2$. Find the value of $x$ and hence the dimensions of the rectangle. **Answer (sketch):** Area: $$(x + 3)(x - 1) = 54$$ Expand: $$x^2 + 3 x - x - 3 = 54 \\ x^2 + 2 x - 3 - 54 = 0 \\ x^2 + 2 x - 57 = 0$$ Solve using quadratic formula: $$x = \frac{-2 \pm \sqrt{4 + 228}}{2} = \frac{-2 \pm \sqrt{232}}{2} = \frac{-2 \pm 2\sqrt{58}}{2} = -1 \pm \sqrt{58}$$ Since $x$ must be positive and larger than 1 (for width $x - 1$ to be positive): $$x = -1 + \sqrt{58}$$ You can leave it in surd form if the question allows, or approximate numerically if required. Then: - Length: $x + 3 = (-1 + \sqrt{58}) + 3 = 2 + \sqrt{58}$ - Width: $x - 1 = (-1 + \sqrt{58}) - 1 = -2 + \sqrt{58}$ --- ### Topic 3: Chemistry (O-Level Pure / Combined) Let’s do a mix of conceptual and calculation questions. #### Q 7 (Basic) – Atomic structure State the number of protons, neutrons and electrons in an atom of $_{17}^{35}\text{Cl}$. **Answer (sketch):** - Protons: 17 (atomic number) - Electrons: 17 (neutral atom) - Neutrons: $35 - 17 = 18$ > “Doing Secondary Science? Pick a topic and practise like it’s a real exam — with clear answers right after.” > [👉 Try Tutorly now and start a Science topic in seconds.](https://tutorly.sg/app)  --- #### Q 8 (Exam-level) – Mole concept Calculate the number of moles in $9.0\text{ g}$ of water, $H_2 O$. (Relative atomic masses: H = 1, O = 16) **Answer (sketch):** Molar mass of $H_2 O$: $$2(1) + 16 = 18\text{ g/mol}$$ Number of moles: $$n = \frac{\text{mass}}{\text{molar mass}} = \frac{9.0}{18} = 0.50\text{ mol}$$ --- #### Q 9 (Hard variant) – Stoichiometry Magnesium reacts with dilute hydrochloric acid according to the equation: $$\text{Mg} + 2\text{HCl} \rightarrow \text{MgCl}_2 + \text{H}_2$$ If $6.0\text{ g}$ of magnesium reacts completely, what volume of hydrogen gas is produced at room temperature and pressure (r.t.p.)? (Relative atomic mass: Mg = 24.0, molar gas volume at r.t.p. = $24\text{ dm}^3\text{/mol}$) **Answer (sketch):** 1. Moles of Mg: $$n(\text{Mg}) = \frac{6.0}{24.0} = 0.25\text{ mol}$$ 2. From the equation, 1 mol Mg → 1 mol $H_2$ So: $$n(H_2) = 0.25\text{ mol}$$ 3. Volume: $$V = n \times 24 = 0.25 \times 24 = 6.0\text{ dm}^3$$ --- You can build full worksheets by: 1. Picking a topic (e.g. “Mole concept limiting reagent”). 2. Drafting 3 easy + 3 medium + 3 hard questions. 3. Going to [https://tutorly.sg/app](https://tutorly.sg/app) and asking: > “I’m a Sec 4 student in Singapore. I created these 3 mole concept questions. Can you: > 1) Solve them step by step, and > 2) Generate 5 more O-Level style questions of similar or slightly higher difficulty, with answers?” Then you’ll have a proper mini worksheet for your own practice or to use with your Preply students (if the level is suitable). --- ## Common mistakes (as a Preply tutor and as an O-Level student) Let’s be honest about the typical traps Singapore students fall into when trying to register as a tutor on Preply while still in Secondary school. ### 1. Overcommitting on lesson slots You might be tempted to open many time slots to get more students. Problem: - You get a few regular students. - You feel bad cancelling. - Your own revision time disappears. - Stress builds up before exams. Fix: - Start with **very limited** availability (e.g. 2–3 hours per week). - Only increase if your grades stay stable or improve. - Before exam periods (mid-years, prelims, O Levels), **reduce** slots. ### 2. Teaching subjects you’re not confident in Some students think: > “If I can make money teaching Physics, why not? I roughly remember the formulas.” This is dangerous because: - You might give **wrong explanations**. - Students may complain or leave bad reviews. - You waste time re-learning topics you don’t even need for your own exams. Fix: - Only list subjects you are at least **B 3 level** (or equivalent) in, or that you genuinely understand. - For O-Level candidates, it’s safer to teach: - Lower Sec topics (Sec 1–2 Math, basic Science) - General English / conversation - Basic primary content, if you’re comfortable ### 3. Ignoring MOE exam formats Preply students may not be using the Singapore MOE syllabus at all. If you focus too much on generic content, you might neglect: - Structured response questions (e.g. SS SBQ, Chem structured questions) - Paper formats (Paper 1 vs Paper 2) - Marking schemes and common O-Level traps Fix: - Regularly revise using **MOE-aligned** materials: - School worksheets - Ten-year series (TYS) - [Tutorly.sg](https://tutorly.sg/app)’s MOE-based explanations When you ask Tutorly for help, specify: > “Explain this as if I’m taking O-Level [subject] in Singapore under MOE syllabus.” This keeps your practice relevant. ### 4. Not using tools to save time Some students still: - Spend 30–40 minutes stuck on one question - Wait days for a teacher or friend to reply During O-Level year, that’s a huge waste of time. Fix: - When you’re truly stuck, get **fast, clear help**: - Open [https://tutorly.sg/app](https://tutorly.sg/app) - Paste the question - Ask for step-by-step explanation + a similar practice question You still need to understand the steps, but at least you’re not wasting half an hour staring at the same page. ### 5. Underestimating mental fatigue Tutoring itself is mentally tiring. After a 1-hour session where you’re explaining algebra, your brain is not in “fresh study” mode anymore. If you schedule: - 2 hours of Preply lessons - Then 3 hours of your own revision …you’ll probably burn out fast. Fix: - After each tutoring session, take a **short break** (10–15 minutes). - Don’t put your **hardest subject** immediately after teaching. - Example: Teach Lower Sec Math → Short break → Revise English vocab (lighter task) → Later in the evening, do A-Math or Pure Chem. --- ## Final thoughts: Should you register as a tutor on Preply as a Singapore Secondary student? Here’s the honest summary: - **Yes**, it’s possible to register as a tutor on Preply from Singapore (if you meet their age and verification requirements). - --- > “Practice PSLE Science questions and get clear, step-by-step answers instantly.” > [👉 Try a question now and see how fast you can improve.](https://tutorly.sg/app)  ## Ready to practise?
