A Level Revision Timetable for 3 Subjects: My Weekly Plan

Quick answer: Revise three A Levels on a fixed weekly rotation, not in long subject-by-subject blocks. Give every subject one 90-minute deep session, one timed past-paper session and one short recall session each week, and rank topics by marks at stake rather than by what feels comfortable. Twelve planned hours beat twenty unplanned ones.

I am in the middle of A Levels right now, alongside finishing IGCSE. History is my favourite subject and English is my strongest, which turned out to be exactly the problem. For most of my first term I revised history because I enjoyed it, told myself the other two would sort themselves out nearer the exams, and got a mock back two grades below what I had assumed. My effort was not low. My distribution was wrong. Everything below is the system I built afterwards, and the numbers in it are the ones I actually run.

Why the GCSE method stops working at A Level

The real change is depth per topic, not the number of subjects. Dropping to three subjects sounds lighter, but one A Level topic can carry more content than an entire GCSE unit, and the questions no longer stop at recall. At GCSE I could read a chapter three times the night before and pick up most of the marks. At A Level that gets you the first mark of a six-mark question and nothing after it.

Three differences to plan around:

• Marks live in the reasoning step. A correct final answer with no working, or a correct opinion with no evidence, is often worth half the marks or fewer.
• Questions are unfamiliar on purpose. AQA, Edexcel, OCR and Cambridge International A Level papers all recombine topics you learned separately, so memorised past answers transfer badly.
• The A to A-star boundary is narrow. It is usually a handful of marks across a whole paper, so precision on questions you can already half-do is worth more than starting a brand new topic.

The weekly rotation for three subjects, with real numbers

Rotate all three subjects every week rather than giving each a dedicated week. A subject left untouched for fourteen days costs you a re-learning session you never budgeted for.

Here is a real term-time week of roughly 12 hours, about 4 hours per subject:

• Monday: Subject 1 deep session, 90 minutes.
• Tuesday: Subject 2 timed exam questions, 60 minutes, plus 20 minutes marking.
• Wednesday: Subject 3 recall, 40 minutes, then Subject 1 recall, 20 minutes.
• Thursday: Subject 2 deep session, 90 minutes.
• Friday: Subject 3 deep session, 90 minutes.
• Saturday: one full past paper under exam timing in a rotating subject, plus 45 minutes marking it properly.
• Sunday: 45 minutes fixing only the errors from Saturday, then stop.

That is 710 minutes, and every subject gets deep work, timed practice and spaced recall inside seven days.

One rule I never break: no two subjects back to back in the same sitting. At GCSE I could switch between three subjects in an evening. At A Level the second subject in a row is always my worst work.

How to spend a 90-minute deep session, step by step

A deep session is not reading. It is a five-part loop, and the timings matter:

1. 5 minutes, blank page. Write everything you remember about last week's topic in this subject. No notes open.
2. 10 minutes, check against the specification. Not your notes, the actual spec document from your board. Mark every bullet you could not produce.
3. 30 minutes, new sub-topic. Turn each spec bullet into a question as you go, so your notes end up as prompts rather than paragraphs.
4. 30 minutes, closed-book exam questions. Two or three on what you just covered. Handwritten, timed.
5. 15 minutes, mark honestly. Against the published mark scheme, then one written line per lost mark saying why it went.

Step 5 is the one everyone skips and it is where the improvement happens. My "why I lost it" lines are almost never "I did not know this". They are things like "gave two reasons, never compared them" or "no units on the final line". Those are fixable in a week; missing knowledge takes a month. Mark My Answer grades a written response against board-style criteria and tells you which assessment objective you missed.

Rank topics by marks at stake, not by comfort

This is the fix for my first-term mistake. Score your confidence in each topic from 1 to 5, then count how many marks that topic was worth across the last four past papers. Priority equals marks per paper multiplied by (5 minus confidence).

A worked example from my own chemistry list:

• Equilibrium: about 14 marks per paper, confidence 2. Score = 14 x 3 = 42.
• Atomic structure: about 6 marks per paper, confidence 1. Score = 6 x 4 = 24.
• Organic mechanisms: about 20 marks per paper, confidence 4. Score = 20 x 1 = 20.

Equilibrium wins, even though atomic structure felt scarier and organic mechanisms is where I most enjoyed spending time. The topic you enjoy is usually the topic you are already good at, which is exactly why revising it returns almost nothing. Redo the scoring every three weeks, because confidence numbers move.

Write in the mark scheme's language while you revise

Command words at A Level are instructions with a mark split behind them, so treat them as content. "Evaluate" and "to what extent" want a judgement plus a reason the other side is weaker. "Justify" wants a choice defended against a named alternative. "Assess" wants criteria stated before you apply them. If your notes are bullet points of fact, you will produce bullet points of fact in the exam and cap yourself at the lowest assessment objective.

So convert as you revise. Instead of a card saying "three causes of X", make one saying "which cause of X mattered most, and why is the second-place cause weaker". That single change moved my history essays more than any amount of extra reading. Building the cards is fast with Flashcards, and my best ones are the linking cards that join two topics from different parts of the spec, because that is where the hard questions live.

The last three weeks before the exam

Stop learning new content and switch entirely to output. One full paper under strict timing every other day, marked the same evening, with an error log you actually reread. Alternate subjects so no paper sits unmarked overnight. Do a couple of papers from a different board in the same subject: a Cambridge International A Level paper phrases a topic differently from an OCR one and exposes gaps your own board hides. A timed Mock Exam works once you have run out of official papers, and for maths the maths hub walkthroughs are quicker than waiting for a teacher.

Sleep is part of the plan, not a reward for finishing it. My marking accuracy on a six-hour night is visibly worse.

Test yourself

1. In the priority formula, which topic ranks higher: 10 marks per paper at confidence 4, or 8 marks per paper at confidence 2?
2. What are the five stages of a 90-minute deep session, in order?
3. Why is a linking card between two spec topics worth more than a definition card?

FAQ

How many hours a week should I revise for three A Levels?

Around 12 hours outside class in term time, roughly 4 per subject, rising to 20 to 25 in the holidays and final weeks. The number matters much less than whether each subject gets deep work, timed practice and recall inside every seven-day window.

Should I revise all three subjects every day?

No. One subject per sitting works better, and each subject appearing two or three times a week is enough spacing. Cramming all three into one evening usually means the third gets your worst attention and has to be redone.

Are past papers from a different exam board worth doing?

Yes, within the same subject. Another board tests the same spec content with unfamiliar wording, which is the closest thing to a new question once you have used up your own board's papers.

What if one subject is dragging the other two down?

Give it one extra session a week for four weeks, not a permanent reallocation. Score its topics with the priority formula first, because the problem is usually two or three specific topics rather than the whole subject.

In short: three A Levels are a distribution problem, not an effort problem. Rotate all three every week, run each deep session as a five-step loop that ends in honest marking, prioritise topics by marks at stake, and spend the last three weeks writing rather than reading. I lost a term learning that, and the fix cost me no extra hours at all.
