Combined Sci

Sec 3 and 4, 5086 / 5088

The Chemistry half of Combined Science, taught by chemistry specialists.

For Sec 3 and 4 Combined Science students who want the Chemistry paper to stop being the weak half. In person at Upper Thomson.

Who it's for

Is this class right for your child?

Students usually join us in one of these situations.

  1. 01

    Chemistry is the weaker half

    Students whose Physics or Biology is fine but Chemistry pulls the grade down.

  2. 02

    Short on lesson time

    Students who want the key ideas taught clearly without padding.

  3. 03

    Unsure what to write

    Students who need to see what a full-mark answer looks like.

Syllabus coverage

Every Combined Science topic, in a sensible order

[PLACEHOLDER] Topic order to be confirmed by the tutors. Follows Combined Science (5086 / 5088).

Particles and bonding

Kinetic particle theory, Atomic structure, Chemical bonding.

Reactions and calculations

Formulae and equations, The mole, Acids, bases and salts, Redox.

Periodic Table and materials

Periodic trends, Metals, Air and the environment.

Organic chemistry

Fuels and crude oil, Alkanes and alkenes.

How lessons run

Four parts, every lesson

The same rhythm each week, so students know what to expect.

  1. 01

    Concept

    A short, clear explanation of the idea, with the why behind it.

  2. 02

    Worked practice

    We solve a question together and show how each line earns a mark.

  3. 03

    Timed questions

    Students attempt exam-style questions under time pressure.

  4. 04

    Feedback

    Marked against the mark scheme, with notes on what to change.

Worked example

What a full-mark answer looks like

One exam-style question, two answers, marked the way an examiner would.

Worked example

[PLACEHOLDER] Original exam-style question written by Chemify

Question

Molten lead(II) bromide, PbBr₂, is electrolysed using inert electrodes. State what is seen at the anode and write the half-equation for the reaction at the cathode. [2]

Weak answer

0 / 2

Bubbles of gas at the anode. Pb → Pb²⁺ + 2e⁻

  • Missed B1Bromine is a reddish-brown vapour, not colourless bubbles.
  • Missed B1Half-equation is reversed: lead ions gain electrons at the cathode.

Strong answer

2 / 2

Anode: reddish-brown vapour (bromine) is given off. Cathode: Pb²⁺ + 2e⁻ → Pb

  • Awarded B1Observation includes colour and state.
  • Awarded B1Balanced reduction half-equation.

Marks follow the examiner's mark scheme: B = independent mark, M = method/reasoning, A = answer.

How much are the fees?

We share fees directly on WhatsApp, so we can tell you the right package for your child's level and schedule.

Ask on WhatsApp
How big are the classes?

[PLACEHOLDER] Classes are kept small so every student gets their work checked in each lesson.

Do you cover the Physics or Biology parts of Combined Science?

No. The Combined Science class covers the Chemistry component only, taught by chemistry specialists.

Can students join in the middle of the year?

[PLACEHOLDER] Yes, if there is a place in the class. We'll share notes for topics already covered.
