Hi, I'm Harry, co-founder of The Degree Gap, a GCSE and A-level tutoring company. We have worked with plenty of students making the jump from GCSE to A-level, and we see the same struggles come up again and again. In this piece I want to walk you through them.

Whether you are in the middle of your GCSEs or have just started A-levels, understanding these pitfalls now will help you avoid them. That means less stress and anxiety around exams, and a clear idea of what to expect from the year ahead.

1. Independent study: when coasting stops working

The biggest issue we see is with genuinely bright students who coast through their GCSEs. They barely revised, understood everything in class and still came away with solid 7s, 8s and 9s across the board.

They arrive at A-level enthusiastic and confident that the same approach will work. It usually doesn't. The step up in difficulty is huge, especially in maths, chemistry and physics, where the content gets much harder and there is far more of it.

What catches most students out is this: at GCSE, it might have taken one or two attempts to understand a topic. At A-level, even the most capable students may need three or four. That can be discouraging. Motivation drops, and students start to wonder why they are putting themselves through it.

If that sounds familiar, know that it is completely normal. It simply means your revision needs to change. Often these students never developed effective revision methods because they never needed them. Now they do.

2. Revision methods that actually work

Start past papers early

The strongest A-level students start past papers as early as possible. In my opinion, your past paper scores are the single best predictor of how you will perform. They highlight your weaknesses so you can target them with flashcards and mind maps, and they let you practise exam technique under realistic conditions.

Read mark schemes and examiner's reports

Across the board, students don't spend enough time with mark schemes and examiner's reports. Read them often. You will subconsciously absorb the language examiners reward in longer answers.

This matters more than ever at A-level, especially in essay-heavy subjects such as A-level History. The groundwork for those subjects starts much earlier, in GCSE English, so it pays to get your essay technique right before you even start sixth form. The step up in scale is big. In GCSE Economics, the longest question is worth 9 marks, while in A-level Economics you will be writing 25-mark essays. That is why picking up the right wording from mark schemes matters so much.

3. Maths: the biggest jump of all

Maths is one of the most popular A-levels, and it is also where we see the most problems with the step up. The reason is the same as before: GCSE Maths can feel easy for naturally mathematical students.

The first week or so of A-level Maths usually recaps GCSE content. Then the difficulty rises sharply. Topics such as differentiation and integration feel completely foreign to students who have mostly worked on algebra, and they demand a new level of understanding. Many students get in touch with us at exactly this point.

Move beyond the textbook quickly

Don't stick with textbook questions for too long. They are not representative of the exam, which is heavily based on problem solving. Get used to exam-style questions as early as you can.

Use old specification papers

A tip I used myself: work through old specification papers. If you are studying Edexcel, the old papers come in gold, silver and bronze versions on the internet, graded by difficulty.

• C1 and C2 gold papers are a great way to build a strong algebra foundation. They are not perfectly matched to the current specification, but they are an excellent starting point.
• C3 and C4 match the current specification less closely, but are still worth doing. Simply skip any questions on topics that are no longer on the specification.
• Mechanics (M1, M2) and Statistics (S1, S2) only partly match the new specification, so use them with more caution.

Do not neglect the large data set in Edexcel Maths

Learn the large data set. Good cheat sheets for the large data set are available online, and I recommend using one, because schools are notoriously poor at teaching it. Sometimes it is worth only a mark or two, but sometimes that first part of a question unlocks parts (b) and (c).

When I sat my A-level Maths exam, the large data set question was on cloud cover, which is measured in oktas on a scale from 0 to 8. You needed that first mark to move on to the next stage of the question.

4. Sciences: choose them for the right reasons

The sciences are extremely demanding at A-level. Physics is very hard, and Chemistry, alongside Further Maths, is among the hardest A-levels you can take. Even very enthusiastic students find them a struggle.

If you are not genuinely interested in science, think carefully before choosing it. Mastering the content takes a great deal of work, and without real enthusiasm it becomes much harder to keep going.

If you want a science-adjacent subject with a lighter load, Psychology is worth a look. It has become one of the most popular A-level subjects. I took it myself and really enjoyed the breadth of topics it covers.

5. Three A-levels or four?

I took four: Maths, Physics, Economics and Psychology. My business partner took three: Economics, Business and Geography.

With four, you have very little free time, and much of your learning has to happen outside school hours. With three, you have far more breathing room. Looking back, I would have dropped Psychology and focused on fewer subjects.

Even so, for very capable students who come to us, four can be the right choice, particularly if there is a good reason to take Further Maths. Further Maths used to be treated almost as a "half subject" alongside Maths, although that is less standard than it once was.

Final thoughts

I could talk all day about A-level choices, the IB, the best subject combinations for university and personal statements, but I'll stop here before this turns into a book.
