Overview

A-Levels are taken over two years (Year 12 and Year 13) and are the primary route to UK university. Since 2017, most A-Levels are linear — meaning all exams are sat at the end of Year 13 based on two full years of content. Students typically take 3–4 A-Level subjects. For courses like Medicine, Law, and Engineering at Oxford, Cambridge, and other Russell Group universities, AAA or A*AA offers are standard.

Year 12 (AS content)VariesOngoingAS-level content forms the foundation; some schools still offer AS exams as internal mocks
Year 13 (A2 content)VariesOngoingDeeper, more complex content building on Year 12 — this is where A* grades are made or lost
Coursework/NEA1 per subjectYear 12–13Non-examined assessment (where applicable): English literature essays, science investigations, art portfolios

Scoring

  • Total: A* (90%+ uniform marks) · A (80%+) · B (70%+) · C (60%+) · D (50%+) · E (40%+) · U (fail)
  • Percentiles: A* is awarded to the top ~8% nationally in each subject (varies by year)
  • Note: For A*, you must average 80%+ across all papers AND score 90%+ on A2 units. Understanding mark scheme language is critical to hitting the top boundary.

Study plan

  1. Year 12 (September–June): Foundations

    • Build strong foundations — Year 12 content is the scaffold for Year 13
    • Practice past exam questions from the FIRST lesson in each topic
    • End of Year 12: full mock using Year 12 past papers

  2. Year 13 (September–January): Build & Deepen

    • Complete Year 13 content while systematically reviewing Year 12
    • Coursework/NEA: drafts must be complete by December
    • Mock exams in January — take them as seriously as the real thing

  3. Year 13 (February–April): Intensive Revision

    • Past papers for every subject — use specification-specific ones
    • Mark your own work against the mark scheme — this is non-negotiable
    • Create revision cards for each topic: key formulas, definitions, model answers

  4. May–June: Exam Season

    • Light revision only — protect energy
    • Review common mistakes from your mock papers
    • Check your exact timetable and exam entry codes

Strategies

Sciences (Biology, Chemistry, Physics)

  • Learn the exact command terms: "describe" vs "explain" vs "evaluate" demand completely different answers
  • Mark scheme language matters — examiners are looking for specific key phrases
  • Practicals: know how to describe methods, identify variables, and evaluate results critically
  • For 6-mark questions: plan before you write. A bullet-pointed plan avoids repetition and missed points

Humanities (History, Geography, Economics)

  • Argument over description: A/A* essays make and defend a clear argument, not just describe events
  • Always address the question directly in your first sentence and return to the question in every paragraph
  • Use specific factual examples — vague generalisations are never awarded top marks
  • Counter-argument then rebut: this structure is explicitly rewarded in mark schemes

Common mistakes

  • Starting revision too late — Year 13 has 2 years of content to cover for each subject
  • Passive revision (reading notes) instead of active recall (past questions, flashcards)
  • Not marking your own work against the official mark scheme — this is the fastest improvement loop
  • Ignoring coursework deadlines — late NEA submissions can cost predicted grades and UCAS offers
  • Attempting too many A-Levels — 3 strong A-Levels beat 4 weak ones for university applications

Frequently asked questions

How many A-Levels do I need for university?

Most UK universities require 3 A-Levels. Medicine, Oxbridge, and a few competitive courses may recommend or require 4. Quality matters far more than quantity.

What is the difference between an A and A* at A-Level?

An A requires 80%+ overall, while an A* requires 80%+ overall AND 90%+ on A2 (Year 13 content) papers. The A* is designed to identify exceptional students.

Can I retake A-Level exams?

Yes. Most candidates retake in the November or June sitting of the following year. You can retake as many modules as you wish, though universities often prefer first-sitting grades.
