How AS & A Level Thinking Skills is really marked

Thinking Skills is marked across twelve papers, and the overall balance in our bank is 727 point-marked questions to 320 calculation questions, with a much smaller 24 pure-levels and 15 points-with-levels. The calculation share is unusually high for a subject that isn't maths — problem-solving papers (11, 12, 13, 31, 32, 33) are dense with numerical puzzles, logic grids and multi-step arithmetic, where you get credit for the reasoning path as well as the final figure.

The points-marked questions dominate the critical-thinking papers (21, 22, 23) and the applied-reasoning papers (41, 42, 43): these ask you to identify a conclusion, spot a flaw, or explain why a piece of evidence is or isn't significant, and each mark corresponds to a specific, nameable point the mark scheme is looking for. Precision in the vocabulary of argument — conclusion, reason, assumption, counter-argument — matters here because the mark scheme distinguishes between them exactly.

A small pure-levels and points-with-levels component (mainly in papers 21–23 and 41–43) asks for a short piece of extended reasoning or evaluation, where the examiner judges overall quality rather than ticking off separate points — but this is a minority of the marks available.

Because so much of the subject rewards showing your working — whether that's an arithmetic method or the logical steps that get you from evidence to conclusion — the biggest single differentiator between candidates isn't cleverness but whether the reasoning is written down at all.

Command words in AS & A Level Thinking Skills

Command wordTimes in our bankWhat it demands
Calculate468Wants a specific numerical answer reached by a valid method — in this subject that usually means working through a real-world puzzle (costs, times, quantities) rather than a formula.
Identify214Asks you to pick out a specific element — a conclusion, an assumption, a flaw — precisely, using the correct term rather than a rough paraphrase.
Explain115Requires you to give the reasoning behind an identification or a judgement, not just restate what you found.
Deduce53Demands a conclusion that follows logically and necessarily from the evidence given — not a guess, an estimate, or a comment on likelihood.
Assess47Asks you to weigh the strength or validity of an argument or claim, considering more than one angle before reaching a judgement.
State39Wants a brief, exact answer with no supporting explanation required.
Evaluate24Requires a judgement on the overall quality or effectiveness of an argument, supported by reasons — typically the most extended, levels-influenced command word in this subject.
Find18Asks for a specific value or solution to be worked out, usually through a defined calculation or logical process.

How to revise with past papers

Because so many marks in the problem-solving papers are for calculation, always write out your working in full when practising past papers, even when you're confident of the answer — it's the only way to check afterwards whether a wrong final figure came from a small slip or a wrong method, and mark schemes for this subject often credit method separately from the final answer.

For the critical-thinking and applied-reasoning papers, drill the vocabulary of argument (conclusion, reason, claim, assumption, counter-argument, flaw) until you use each term precisely — a large share of marks lost in this subject come from candidates using the wrong term for the right idea, not from missing the idea entirely.

Practise timing separately for the numerical and reasoning sections of a paper, since they demand different kinds of thinking — rushing a logic problem to save time for an essay-style answer (or vice versa) is a generic risk worth planning for explicitly.

FAQs

Is Thinking Skills mostly a maths subject?

Not exactly — in our bank calculation questions make up 320 of 1,086 questions, a large minority, with point-marked reasoning questions still the biggest single category at 727.

Why do I need to show working on a logic puzzle?

Without working shown, it isn't possible to tell where an incorrect answer went wrong, which limits partial credit — so showing your reasoning is generally good exam practice.

What's the difference between a conclusion and a claim in this subject?

The terms are used precisely in this subject's mark schemes and shouldn't be treated as interchangeable: a conclusion is what the argument sets out to establish, while a claim is any assertion made along the way.

Are the essay-style questions a big part of the marks?

No — pure-levels and points-with-levels questions together make up 39 of the 1,086 questions in our bank, a small share compared with the points and calculation questions.
