How many A-Levels should I take?

Three is standard and is what most universities ask for. A fourth, such as Further Maths, can help for some courses but is rarely required. Strong grades in three are usually better than average grades in four.

Can I change A-Level subjects after starting?

Many schools allow changes in the first few weeks of Year 12. After that it becomes harder to catch up, so talk to your school early.

How important are predicted grades?

Very. Universities use predicted grades, usually set in Year 13, to decide on offers. Year 12 work and mocks often shape them.

GCSE to A-Level: How to Handle the Step Up

Moving from GCSE to A-Level

By the Top Tutors Online editorial team · Updated 4 November 2026 · 3 min read

The short answer

A-Levels go deeper than GCSEs, with fewer subjects, more independent study and questions that reward analysis over recall. The step up is easiest for students who choose subjects they enjoy and that keep their university options open, review notes every week from the start of Year 12, and get help early if a topic does not click.

Key points

Most students take three A-Levels over two years, graded A* to E.
Expect about as much independent study as class time.
Check university entry requirements before choosing subjects.
Weekly review stops gaps from building up before mocks.
Maths, the sciences and essay subjects each need different study habits.

Why A-Levels feel harder

At GCSE, students cover many subjects at a broad level. At A-Level they usually take three subjects in much more depth. Questions ask students to apply ideas to new situations, evaluate evidence and write extended arguments. Most A-Levels are assessed by exams at the end of Year 13, so steady work across both years matters.

Choosing subjects

Pick subjects you enjoy and do well in, because motivation carries you through two years.
Check entry requirements for courses you might apply to. Medicine usually needs chemistry, engineering usually needs maths and often physics, and some economics courses prefer maths.
Think about the mix: essay subjects and problem-solving subjects use different skills, and many students like a balance.
Ask whether Further Maths would strengthen an application for maths, physics, engineering or computer science.

Study habits that help

Review every week. Turn class notes into summaries or flashcards within a few days.
Read beyond the textbook. Articles, podcasts and books build the understanding examiners and universities look for.
Practise exam questions early. Do not wait until Year 13 to see what is asked.
Ask questions. Use teachers' office hours and get help as soon as something is unclear.

Subject-specific advice

Maths and sciences: the jump in algebra and problem solving is the most common challenge, so secure GCSE algebra over the summer. Essay subjects such as English, history and economics need argued, evidenced paragraphs. Practise planning answers, not just knowing content. Languages: regular listening and reading in the language makes a big difference.

When extra help is worth it

An A-Level tutor is most useful early in Year 12 to close gaps from GCSE, before Year 12 mocks, and in the run-up to predicted grades, which matter for UCAS applications in the autumn of Year 13.
