Preply Physics Tutor vs Local Singapore Options: What Really Matters

You’ve probably seen Preply ads: lots of tutors, many from overseas, different hourly rates. On paper, it looks great.

But for O Level Physics in Singapore, there are a few specific things you must consider.

1. Syllabus Fit: “Physics is physics” … but exams aren’t

Yes, physics laws are universal. But exam styles are not.

Preply physics tutor (typical scenario):

• Many tutors teach IB, AP, GCSE, generic high school physics
• They may not know:
  • Our O Level formula sheet (what’s given vs what you must memorise)
  • MOE’s emphasis on data-based questions, planning experiments, and structured answers
  • The style of questions like: “State and explain”, “With the aid of a diagram”, “Suggest and explain”

Local Singapore options (school teacher / home tutor / AI built for MOE):

• Specifically follow MOE / O Level syllabus
• Know that:
  • “Weight” vs “mass” is a favourite trap in MCQs
  • Practical questions often test on sources of error, improvements, and graph interpretation
  • Kinematics questions often combine speed-time graphs with area under graph = distance

This difference sounds small, but in Paper 2, one misunderstood command word can cost you 2–4 marks.

That’s why using a tool built specifically for Singapore students, like Tutorly.sg, can be a lot more efficient than explaining to an overseas tutor what “Sec 4 Pure Physics” even is.

---

2. Cost, Flexibility, and “Dead Time”

Preply physics tutor:

• You pay by the hour
• If you’re tired or unprepared, that 1 hour can become:
  • 20 mins of warming up
  • 20 mins of revising what you already know
  • 20 mins of actual new learning

You’re paying full price for that.

Local home tutor / centre:

• Similar issue: fixed slots, fixed pace
• If you miss a session, it’s usually just gone

Tutorly.sg (24/7 AI tutor built for SG students):

• You can ask questions any time, even 11.45pm before a test
• No “wasted warm-up time” – you jump straight into:
  • “Explain why the reading on the ammeter is zero”
  • “Show me step-by-step how to solve this kinematics question”
• Thousands of students in Singapore already use it for last-minute help, and it’s even been mentioned on Channel NewsAsia (CNA), so you’re not exactly “experimenting” with something unknown.

You don’t have to choose only one option, by the way. Many students use a mix: school + maybe a human tutor + Tutorly.sg as their on-demand helper.

---

3. Communication & Examples

Physics isn’t just about formulas; it’s about understanding what’s going on.

Potential issues with some Preply tutors:

• Different units or conventions (e.g. using $g = 9.8 \text{ m/s}^2$ vs $10 \text{ m/s}^2$ in certain questions)
• Examples based on foreign contexts $snow, imperial units, US-style labs$
• Not familiar with TYS-style phrasing like:
  • “Explain, in terms of forces, why…”
  • “Use ideas about momentum to explain…”

Local-focused tools (like Tutorly.sg):

• Use MOE-style language and question styles
• When you ask about “O Level Physics moments question”, it knows the kind of lever diagrams and typical marking schemes you’re dealing with
• Uses SI units, the same constants, and similar setups to your school worksheets

This may seem minor, but when you’re stressed and tired, having familiar phrasing really helps.

---

4. Availability and Consistency

Preply tutor:

• You depend on that specific person’s schedule
• If they fall sick, change time zone, or get fully booked, you might be stuck near exam period

Local tutor:

• Same issue: limited slots, especially near prelims and O Levels

Tutorly.sg:

• Always available, because it’s web-based and runs 24/7
• You just go to https://tutorly.sg/app and start asking questions
• No need to coordinate timing, no travel, no waiting

This is especially useful if your free time is random (CCA, projects, tuition, family).

Step-by-step Tutorial: Using Tutorly.sg Like a Serious Physics Student

If you decide to try a Preply physics tutor, you can still use Tutorly.sg alongside. Here’s a practical workflow that works well for many Sec 3–4 students.

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

Step 1: Pick a topic you’re currently weak at

Examples:

• Sec 3 / 4 Pure Physics: Kinematics, Dynamics, Turning Effects, Work/Energy/Power
• Combined Science (Physics): Light, Electricity, Practical skills

Don’t try to “do everything” in one night. Choose one topic.

Step 2: Go to Tutorly.sg and ask a targeted question

Head to:
https://tutorly.sg/app

Then try questions like:

• “Explain step-by-step how to draw a ray diagram for a converging lens forming a real image.”
• “Show me how to solve an O Level style question on moments with two unknown forces.”
• “Give me a structured answer for: explain why the reading on the ammeter increases when the resistance decreases.”

Tutorly will give you:

• A clear explanation
• A step-by-step worked solution for the final answer
• Often, more than one similar question so you can practise

You can then tweak your question:

• “Give me a harder version”
• “Test me with a question where the pivot is not at the end of the beam”
• “Give me a question with a speed-time graph that changes gradient twice”

Step 3: Use it as a “concept checker” after tuition / class

After your school lesson or Preply session, you can go back and:

• Type in a question you half understood
• Ask: “Explain this in a simpler way” or “Show me a step-by-step method”

This is where AI shines: you can ask the same thing in many different ways without feeling paiseh.

Step 4: Simulate exam conditions

Once you understand a concept, tell Tutorly:

• “Give me 5 O Level style MCQs on pressure with increasing difficulty.”
• “Give me a structured question $8–10 marks$ on kinetic model of matter.”

Do the questions without looking at the solution.

Then:

• Check only the final answer yourself
• If you’re wrong, read the step-by-step solution to see where your thinking differed

Remember: Tutorly doesn’t check each step of your working, but it does show a full solution path so you can compare.

Step 5: Build a mistake log

Every time you get something wrong:

• Note the topic (e.g. “Dynamics – resultant force direction”)
• Note the reason:
  • Misread question
  • Mixed up units
  • Forgot to convert minutes to seconds
  • Confused mass vs weight

Then, you can ask Tutorly:

• “Give me 3 more questions that test the same concept as this mistake.”

You’re basically turning each mistake into targeted practice, which is what good tutors do manually.

Exam Strategy Guide for O Level Physics (and Combined Physics)

Let’s shift from platforms to how you should actually study for exams.

1. Know the paper structure

For O Level Pure Physics (6091), you typically face:

• Paper 1: MCQ $40 marks$
• Paper 2: Structured and free-response $80 marks$
• Paper 3 or 4: Practical or Alternative to Practical

For Combined Science (Physics), the weighting is different but the style is similar: MCQs + structured questions.

Why this matters:

• Paper 1 tests breadth – lots of topics quickly
• Paper 2 tests depth – clear explanations, diagrams, calculations
• Practical / Alt-to-Practical** tests your understanding of experiments, graphs, and errors

Your study strategy must cover all three, not just “do TYS from start to end”.

---

2. Weekly study structure (realistic for busy students)

Try this simple framework:

Mon–Thu (short sessions, 30–45 min):

• 1 day: Theory review $notes + concept questions using Tutorly$
• 2 days: Practice 5–10 MCQs each (mark immediately, note mistakes)
• 1 day: 1–2 structured questions from TYS / school paper

Fri / Sat (longer, 1–1.5 hours):

• Do a mini mock:
  • 20 MCQs $timed, 25–30 mins$
  • 1 long structured question $8–10 marks$
• Mark and review using:
  • Mark scheme
  • Tutorly for any question you can’t understand

Sun:

• Light review: just go through your mistake log
• Use Tutorly to re-explain 1–2 concepts that still feel shaky

---

3. How to answer structured questions for full marks

A lot of students know the concept but still lose marks because their answers are not exam-style.

Use this pattern:

1. Define / state the principle (if relevant)

   • Example (moments): “For a body in equilibrium, the sum of clockwise moments about a point equals the sum of anticlockwise moments about the same point.”

2. Apply it to the question

   • Set up the equation with correct distances and forces

3. Show working clearly with units

4. Conclude with a statement

   • “Therefore, the weight of the object is 12 N.”

You can ask Tutorly:

• “Show me a full-mark answer for this question, including explanation, not just the final number.”

Then compare your own style with that.

---

4. Practical / Alt-to-Practical strategy

Even if you’re not doing the actual practical $Alt-to-Practical paper$, you still need to:

• Describe good experimental design
• Identify sources of error and improvements
• Interpret graphs: gradient, intercept, linearisation

You can practise by asking Tutorly:

• “Give me an O Level style question where I must describe an experiment to measure the density of an irregular solid.”
• “Give me a question where I interpret a graph to find acceleration.”

Then focus on:

• Using proper terms: “parallax error”, “zero error”, “systematic error”, “random error”
• Describing how to improve, not just “be more careful”

---

Worksheet Practice (With Hard Variants)

Let’s do some actual practice, the way I would in a tuition session. Try these questions on your own first, then use Tutorly to check your answers and see full solutions.

Topic 1: Kinematics (Speed, Velocity, Acceleration)

Q 1 (Basic MCQ)

A car travels at a constant speed of $20 \text{ m/s}$ for 3 minutes. What distance does it travel?

A. 60 m
B. 180 m
C. 3600 m
D. 4000 m

Think: convert minutes to seconds first.

---

Q 2 (Structured – Medium)

A cyclist moves in a straight line. The graph below shows his velocity against time:

• From $0$ to $5$ s, velocity increases uniformly from $0$ to $10 \text{ m/s}$
• From $5$ to $15$ s, velocity remains constant at $10 \text{ m/s}$
• From $15$ to $20$ s, velocity decreases uniformly from $10 \text{ m/s}$ to $0$

(a) Calculate the acceleration between $0$ and $5$ s.
(b) Calculate the total distance travelled in 20 s.
(c) Is the motion between $15$ and $20$ s acceleration or deceleration? Explain.

If you’re stuck, ask Tutorly:

“Show me step-by-step how to find the distance from a velocity-time graph with three stages.”

---

Q 3 (Hard Variant)

A car is moving along a straight road. Its velocity-time graph is as follows:

• It accelerates uniformly from rest to $15 \text{ m/s}$ in $t_1$ seconds
• It then travels at constant velocity for 30 s
• Finally, it decelerates uniformly at $0.5 \text{ m/s}^2$ to rest in 20 s

The total distance travelled is 825 m.

(a) Find the time taken to decelerate from $15 \text{ m/s}$ to rest.
(b) Hence, find $t_1$.
(c) Calculate the acceleration during the first stage.

This is a classic exam-style combined reasoning question: you need to use area under the graph and kinematics formulas.

---

Topic 2: Moments (Turning Effects of Forces)

Q 4 (Basic)

A 2.0 m uniform beam of weight 200 N is supported at its centre. A 100 N weight is hung 0.5 m from the left end.

(a) About the centre of the beam, what is the moment of the 100 N weight?
(b) State whether the beam will rotate, and in which direction.

---

Q 5 (Medium – Non-uniform pivot)

A 3.0 m beam is pivoted at a point 1.0 m from its left end. A 300 N weight is hung at the left end. A 200 N weight is hung at the right end.

(a) Taking moments about the pivot, determine whether the beam is in rotational equilibrium.
(b) If not, which side will move downwards?

If you’re unsure how to set the distances, ask Tutorly:

“Explain how to measure perpendicular distance for moments when the pivot is not at the end of the beam.”

---

Q 6 (Hard Variant – Unknown force)

A uniform beam AB of length 4.0 m and weight 400 N is supported horizontally by two vertical forces at A and B. A 300 N load is placed 1.0 m from end A.

(a) Taking moments about A, find the reaction force at B.
(b) Hence, find the reaction force at A.

This type of question appears frequently in O Level Physics. You must:

• Use equilibrium of moments to find one reaction
• Use equilibrium of forces $upward = downward$ to find the other

---

Topic 3: Electricity (Ohm’s Law, Series/Parallel)

Q 7 (Basic MCQ)

A 6 Ω resistor and a 3 Ω resistor are connected in series to a 9 V battery. What is the current in the circuit?

A. 0.5 A
B. 1.0 A
C. 1.5 A
D. 3.0 A

---

Q 8 (Medium – Mixed circuit)

A 12 V battery is connected to three resistors as follows:

• A 4 Ω resistor in series with
• A parallel combination of 6 Ω and 6 Ω

(a) Find the total resistance in the circuit.
(b) Find the current supplied by the battery.
(c) Find the current in each 6 Ω resistor.

You can ask Tutorly:

“Show me step-by-step how to simplify a circuit with one resistor in series with two equal resistors in parallel.”

---

Q 9 (Hard Variant – Internal resistance style)

A 12 V battery is connected to a variable resistor. When the resistance is set to 4 Ω, the current is measured to be 2.0 A.

(a) Calculate the total resistance of the circuit.
(b) Hence, determine the internal resistance of the battery.

This is a higher-level style question that sometimes appears in more challenging school papers.

Common Mistakes When Using Online Physics Tutors (and How to Avoid Them)

Whether you use a Preply physics tutor, a local tutor, or Tutorly.sg, these are the patterns I see over and over.

1. Treating tutoring as a “replacement” for school

Some students think:

“Never mind, I’ll just ask my Preply tutor / AI tutor later.”

This leads to:

• Not paying attention in class
• Not attempting homework properly
• Using tuition time just to copy solutions

Better approach:

• Treat school lessons as your first exposure
• Use tutors (human or AI) as:
  • Clarifiers
  • Practice generators
  • Feedback providers

---

2. Not being specific with your questions

Vague:

“I don’t understand electricity.”

Better:

“I don’t understand how to calculate total resistance when there is a mix of series and parallel resistors.”

With Preply or a human tutor, you save time.
With Tutorly, you get more targeted explanations and practice.

---

3. Ignoring units and significant figures

Common exam killers:

• Using minutes instead of seconds
• Forgetting to convert cm to m
• Writing answers without units

Make it a habit:

• Every time you write a formula, check units
• Every time you get a final answer, attach correct units $N, J, W, m/s, etc.$

You can even ask Tutorly:

• “Give me 5 MCQs where the main trick is unit conversion.”

---

4. Memorising answers instead of methods

Especially with TYS and school papers, some students:

• Memorise the exact phrasing of explanations
• Panic when the question changes slightly

What you should focus on instead:

• The principle (e.g. conservation of momentum, Ohm’s law, kinetic model)
• The structure of the explanation

For example, for “Why is there a terminal velocity?” type questions, your structure is:

1. As speed increases, air resistance increases
2. Eventually, air resistance equals weight
3. Resultant force becomes zero
4. Acceleration becomes zero, velocity becomes constant

Tutorly can help by:

• Giving you model answers
• Rephrasing them in simpler language
• Letting you practise similar questions with different contexts

---

5. Only doing easy questions

This is where many students go wrong. They:

• Do only the questions they’re comfortable with
• Avoid graphs, experimental design, or long calculations

Then in exams, they get stuck on the harder variants that carry more marks.

How to fix this:

• After you feel comfortable with basics, force yourself to attempt:
  • Graph questions
  • Multi-step calculations
  • Questions that combine topics $e.g. kinematics + forces$

Tell Tutorly:

• “Give me a hard O Level style question on [topic].”
• “Give me a question that combines moments and weight of the beam.”

This way, you’re training yourself for the upper band of marks, not just passing.

---
