Step-by-step tutorial

Let’s break JC 1 H 2 Math into core pillars you’ll definitely see in exams and promos:

Functions & Graphing
Quadratics & Inequalities
Sequences & Series
Differentiation
Integration
Vectors $2 D & 3 D$
Probability & Statistics $basic part in JC 1 if your school starts early$

Instead of just listing formulas, I’ll walk through how to learn each pillar, with mini-tutorials and “what to focus on”.

1. Functions & Graphing: Your foundation for everything

If you’re weak here, almost every topic later becomes harder.

Core ideas to master:

Domain and range (including restricted domains)
Composite functions $f(g(x))$ and inverse functions $f^{-1}(x)$
Sketching graphs: transformations, asymptotes, key points
Exponential and logarithmic functions

Mini-tutorial: Inverse functions

You must be comfortable with:

Finding the inverse
For $y = f(x)$ , to find $f^{-1}(x)$ :
- Swap $x$ and $y$
- Make $y$ the subject
Example:
$y = \frac{2 x - 3}{5}$
Swap: $x = \frac{2 y - 3}{5}$
Rearrange:
$5 x = 2 y - 3 \Rightarrow 2 y = 5 x + 3 \Rightarrow y = \frac{5 x + 3}{2}$
So $f^{-1}(x) = \dfrac{5 x + 3}{2}$ .
Checking if inverse exists
- Function must be one-to-one on the given domain
- Often you’ll restrict the domain to make it one-to-one
Graph relationship
- Graph of $y = f^{-1}(x)$ is the reflection of $y = f(x)$ across $y = x$

How to practise this topic effectively:

Do basic questions until you can find inverses without thinking too much.
Then move to questions that involve domain restrictions and graph interpretations.
Finally, try questions where they mix log, exp, inverse, and composite functions together.

On Tutorly.sg, you can type something like:

“I’m doing JC 1 H 2 Math functions. Give me 5 questions on inverse functions with domain restrictions, from easy to hard, and show me full worked solutions.”

It will generate questions aligned to MOE H 2 Math and walk you through the steps after showing the final answer.

2. Quadratics & Inequalities: Beyond ‘solve for x’

This isn’t just Sec 3/4 A Math repeated. In H 2 Math, you need to:

Work with quadratic expressions in disguise (e.g. $x + \frac{1}{x}$ )
Solve inequalities involving rational functions
Interpret inequalities in terms of graphs and ranges of values

Mini-tutorial: Quadratic inequalities using graphs

Example:
Solve the inequality
$\frac{x+1}{x-2} > 0.$

Step 1: Find critical points

Numerator zero: $x + 1 = 0 \Rightarrow x = -1$
Denominator zero (vertical asymptote): $x - 2 = 0 \Rightarrow x = 2$

Step 2: Draw sign diagram

Intervals: $(-\infty, -1)$ , $(-1, 2)$ , $(2, \infty)$

Test points:

$x = -2$ : $\frac{-2+1}{-2-2} = \frac{-1}{-4} > 0$
$x = 0$ : $\frac{1}{-2} < 0$
$x = 3$ : $\frac{4}{1} > 0$

So $\frac{x+1}{x-2} > 0$ on $(-\infty, -1)$ and $(2, \infty)$ .

Step 3: Check equality and restrictions

“ $>$ ” means strictly greater, so exclude $x = -1$
Denominator cannot be zero, so exclude $x = 2$

Final answer:
$x \in (-\infty, -1) \cup (2, \infty).$

This kind of question shows up often in promos.

3. Sequences & Series: Where many JC 1 s start to panic

Here you meet:

Arithmetic and geometric progressions $AP/GP$
Sum to infinity
Recurrence relations (e.g. $u_{n+1} = ku_n + c$ )
Sigma notation $\sum$

Mini-tutorial: Geometric series with sum to infinity

If $|r| < 1$ , then:

Sum of first $n$ terms of GP:
$S_n = a \frac{1 - r^n}{1 - r}$
Sum to infinity:
$S_\infty = \frac{a}{1 - r}$

Example:
A GP has first term 5 and common ratio 0.8. Find the sum to infinity.

$S_\infty = \frac{5}{1 - 0.8} = \frac{5}{0.2} = 25.$

Where it gets harder in H 2 Math:

They mix AP + GP in one question
They embed sequences in real-life context (e.g. depreciation, population growth)
They ask you to derive a recurrence relation yourself

A good way to practise is to ask Tutorly:

“Give me 3 JC 1 H 2 Math questions involving both AP and GP in the same problem, including at least one where I have to form a recurrence relation.”

4. Differentiation: Techniques + interpretation

You’ve seen basic differentiation before, but H 2 Math pushes it further:

Product rule, quotient rule, chain rule
Implicit differentiation
Tangents, normals, stationary points
Increasing/decreasing functions, maxima/minima
Simple optimisation problems

Mini-tutorial: Using chain rule properly

Example: Differentiate $y = (3 x^2 - 4 x + 1)^5$ with respect to $x$ .

Let $u = 3 x^2 - 4 x + 1$ , so $y = u^5$ .

Then:

$\frac{dy}{du} = 5 u^4$
$\frac{du}{dx} = 6 x - 4$

By chain rule:
$\frac{dy}{dx} = \frac{dy}{du} \cdot \frac{du}{dx} = 5 u^4(6 x - 4) = 5(3 x^2 - 4 x + 1)^4(6 x - 4).$

In exams, they often embed chain rule inside more complicated functions, or combine it with product/quotient rules.

Key exam skill:
After differentiating, you must be able to:

Interpret what the derivative means (e.g. gradient, rate of change)
Use it to find turning points and classify them $max/min$ using sign diagrams or second derivative

5. Integration: Reverse of differentiation (but not always obvious)

You’ll learn:

Basic integration rules
Substitution method
Integration by parts
Definite integrals & area under curves

Mini-tutorial: Substitution

Example:
Evaluate
$\int (2 x + 1)e^{x^2 + x} \, dx.$

Let $u = x^2 + x$
Then $\frac{du}{dx} = 2 x + 1 \Rightarrow du = (2 x+1)\,dx$

So:
$\int (2 x + 1)e^{x^2 + x} \, dx = \int e^u \, du = e^u + C = e^{x^2 + x} + C.$

The trick is to spot a function and its derivative inside the integrand.

6. Vectors: 2 D and 3 D geometry in algebra form

Many students struggle here because it’s a new way of thinking.

You need to know:

Vector notation: $\vec{a}$ , $\vec{AB}$ , coordinates form
Magnitude and direction
Dot product (scalar product) and angle between vectors
Equations of lines and planes
Intersection of lines, line-plane, plane-plane $in JC 2 usually, but basics start in JC 1$

Mini-tutorial: Equation of a line

Given a point $A(1,2,3)$ and a direction vector $\vec{d} = \begin{pmatrix}2 \\ -1 \\ 4\end{pmatrix}$ , the line $l$ can be written as:

$\vec{r} = \begin{pmatrix}1 \\ 2 \\ 3\end{pmatrix} + \lambda \begin{pmatrix}2 \\ -1 \\ 4\end{pmatrix}, \quad \lambda \in \mathbb{R}.$

Where $\vec{r}$ is the position vector of a general point on the line.

7. Probability & Statistics (if your school starts in JC 1)

Some JCs start the statistics portion in JC 1:

Basic probability rules
Conditional probability
Permutations and combinations (sometimes revisited here)

You don’t need to be a stats genius yet, but you must be solid in:

$P(A \cap B)$ , $P(A \cup B)$
Using tree diagrams or tables
Understanding “given that” questions (conditional probability)

Exam strategy guide

Content knowledge alone is not enough. JC exams (especially promos) are about application and speed under pressure.

Study smarter with Tutorly.sg

Here’s how to approach JC 1 H 2 Math exams in Singapore, from school tests to promos.

1. Know the weightage and pattern

Typically for JC 1:

Papers are around 2 hours to 2.5 hours
Mix of short questions and longer structured questions
Topics are often integrated $e.g. functions + calculus, sequences + inequalities$

Look at your school’s past year promos or mid-years. You’ll notice:

Question 1–2: Shorter, more direct (functions, algebra, simple calculus)
Middle questions: Vectors, sequences, more thinking required
Last 1–2 questions: Heavier application or multi-part questions

Plan your time roughly like:

First 20–30 mins: Clear the easier questions quickly but accurately
Middle 60–75 mins: Tackle medium-difficulty questions
Last 20–30 mins: Hardest questions + checking

2. Marks are for method, not just final answer

Cambridge and JC markers reward clear working. Even if you can’t fully solve, you can still collect method marks.

When answering:

Always show key steps, especially:
- Factorisation
- Substitution
- Differentiation/integration working
- Use of formulas $e.g. AP/GP sums$
For “Hence” questions, use your previous result. Don’t re-derive from scratch.

A good habit when practising:

After solving a question, ask: “If I lost my final answer, would the marker still know what I did?”
If the answer is no, your working is too thin.

On Tutorly.sg, when you ask for a solution, you’ll see step-by-step working laid out clearly. Use this to compare with your own style:

Are you skipping logical steps?
Are you using proper notation?

3. How to handle “I don’t know how to start”

This is a huge problem in JC 1. You open the paper, see a long question, and your brain freezes.

Here’s a simple rescue plan:

Underline what is given and what is asked.
Write down relevant formulas or definitions on the side.
Ask yourself: “Which topic is this really about?”
- If it’s sequences, think $u_n$ , $S_n$ , AP/GP.
- If it’s vectors, think about lines, planes, dot product.
Try to solve just the first part of the question. Often, later parts depend on your answer from part (i).

If you’re stuck while revising at home, this is exactly where Tutorly.sg is useful:

You can paste the question in and ask,

“Give me a hint for part (i) only, don’t show full solution yet.”
Then try again. If still stuck, ask for the next hint or the full solution.

This way, you train your brain to start questions instead of giving up immediately.

4. Promos vs A Levels mindset

Even though you’re in JC 1, A Levels style has already started:

Questions are less about routine calculation
More about reasoning and connecting topics

If you build A-Level style habits now:

Writing clear, logical working
Explaining reasoning for inequalities, maxima/minima, etc.
Being comfortable with wordy application questions

You’ll find JC 2 and the actual A Levels much less scary.

Worksheet practice

You can’t “understand” your way to an A for H 2 Math. You need serious practice, including hard variants that feel worse than your tutorials.

Let’s talk about:

How to structure your own practice
Sample worksheet-style questions (with easy → medium → hard variants)
How to use Tutorly.sg as your personal “worksheet generator”

1. How to structure practice each week

For JC 1, a realistic weekly plan might look like:

2–3 days: Do your school tutorial questions properly (not copying friends).
1–2 days: Extra practice:
- 3–5 easier questions to build confidence
- 2–3 medium questions
- 1–2 hard exam-style questions

When you’re closer to tests or promos:

Add timed practice $e.g. 1 hour, do 3–4 questions without distractions$
Simulate the exam environment: no notes, no checking answers until the end

Instead of hunting for random questions online, you can ask Tutorly.sg:

“Create a 10-question JC 1 H 2 Math worksheet on differentiation, with 4 easy, 4 medium, and 2 hard exam-style questions. After each question, show me the final answer only. At the end, show me full step-by-step solutions.”

You get fresh questions each time, aligned to MOE H 2 Math, and you don’t waste time flipping through multiple PDFs.

2. Sample worksheet: Functions & inequalities

Let’s build a mini worksheet together, including hard variants.

Q 1 (Easy) – Domain and range

Find the domain and range of $f(x) = \sqrt{5 - 2 x}$ .

Key idea:

Square root requires $5 - 2 x \ge 0$
Then find range from resulting interval of $x$

Q 2 (Medium) – Composite & inverse

Given $f(x) = 3 x - 1$ and $g(x) = \dfrac{1}{x+2}$ , find:

a) $f(g(x))$
b) $g(f(x))$
c) $(f \circ g)^{-1}(x)$

Q 3 (Medium) – Quadratic inequality

Solve the inequality
$x^2 - 5 x + 6 \le 0.$

Key idea:

Factorise
Use sign diagram or graph interpretation

Q 4 (Hard) – Rational inequality (exam-style)

Solve the inequality
$\frac{x^2 - 4 x - 5}{x + 1} < 0.$

Thinking path:

Factorise numerator: $x^2 - 4 x - 5 = (x-5)(x+1)$
Expression becomes $\dfrac{(x-5)(x+1)}{x+1}$
But you cannot cancel blindly without considering $x \ne -1$
Solve carefully and represent solution set

This is the type of question many JC 1 students mishandle in exams.

3. Sample worksheet: Differentiation (with hard variant)

Q 5 (Easy) – Basic differentiation

Differentiate $y = 4 x^3 - 3 x^2 + 2 x - 7$ with respect to $x$ .

Q 6 (Medium) – Product rule

Differentiate $y = x^2 e^x$ with respect to $x$ .

Q 7 (Medium) – Stationary point

Given $y = x^3 - 3 x^2 + 2$ ,

a) Find $\dfrac{dy}{dx}$ .
b) Find the coordinates of the stationary points.
c) Determine the nature $max/min$ of each stationary point.

Q 8 (Hard) – Application / optimisation

A rectangular field is to be fenced on three sides (two widths and one length), with the fourth side along a straight river that needs no fencing. You have 120 m of fencing material. Let the width be $x$ m.

a) Express the area $A$ of the field in terms of $x$ .
b) Find the value of $x$ that maximises the area.
c) Find the maximum area.

This is classic JC 1 optimisation, and schools love this style.

4. Sample worksheet: Vectors (with hard variant)

Q 9 (Medium) – Dot product

Given $\vec{a} = \begin{pmatrix}1 \\ 2 \\ -1\end{pmatrix}$ and $\vec{b} = \begin{pmatrix}2 \\ -1 \\ 3\end{pmatrix}$ , find:

a) $\vec{a} \cdot \vec{b}$
b) The angle between $\vec{a}$ and $\vec{b}$

Q 10 (Hard) – Line intersection (challenging)

Line $l_1$ is given by
$\vec{r} = \begin{pmatrix}1 \\ 0 \\ 2\end{pmatrix} + \lambda \begin{pmatrix}2 \\ 1 \\ -1\end{pmatrix},$
and line $l_2$ is given by
$\vec{r} = \begin{pmatrix}3 \\ -1 \\ 1\end{pmatrix} + \mu \begin{pmatrix}1 \\ 2 \\ k\end{pmatrix},$
where $k$ is a constant.

a) Find the values of $\lambda$ and $\mu$ for which $l_1$ and $l_2$ intersect, in terms of $k$ .
b) Hence, find the value of $k$ for which $l_1$ and $l_2$ intersect at exactly one point.

This is already closer to A Level style but can appear in stronger JC 1 papers.

5. Turning Tutorly.sg into your personal worksheet machine

Instead of passively doing only school tutorials, you can actively create practice for yourself:

On https://tutorly.sg/app, you can:

Pick Level: JC 1 / JC 2, Subject: H 2 Math
Then ask things like:
- “Generate 15 JC 1 H 2 Math questions on sequences and series, with 5 easy, 5 medium, 5 hard. Show final answers only first.”
- “Give me 8 vector questions focusing on lines in 3 D, including at least 3 intersection/angle questions.”

When you’re done, you can say:

“Now show me step-by-step worked solutions for Q 3, Q 5 and Q 7 only — I got those wrong.”

This is a very efficient way to build targeted practice around your weak topics.

Common mistakes

Let’s talk about the things that actually cause students to fail JC 1 H 2 Math in Singapore, even if they’re hardworking.

1. Treating JC 1 like Sec 4

Common mindset:

“I’ll just pay attention in class, do tutorials near the deadline, and cram before tests.”

This might have worked for O-Level A Math.
For H 2 Math, this usually leads to:

Confusion after the first few topics
Panic before promos
Scraping a borderline pass or failing

Fix:

Revise weekly, not just before tests.
After each lecture or tutorial, spend 20–30 minutes reviewing and doing 2–3 extra questions.

You can use Tutorly.sg for these quick top-ups:

“Give me 3 mixed JC 1 H 2 Math questions on today’s topics: functions and inequalities. Medium difficulty only.”

2. Memorising formulas without understanding

For example:

Using $S_n$ formula without knowing when it’s AP or GP
Differentiating blindly without thinking about what the derivative means
Applying integration by parts everywhere, even when substitution is easier

In exams, questions are set to punish pure memorisation. They twist the context slightly, and suddenly your memorised pattern doesn’t work.
