A-Level Exam Preparation: Everything You Need to Know

You remember the nerves before your GCSEs, that knot in your stomach, convinced knowing the content would be enough to see you through. A-level exams raise the stakes higher still. Real exam preparation is what closes that gap, in how you handle the paper itself under pressure, not just what you've revised.

‍

To ace your A-level exams, match every answer to its command word, budget your time by mark value, and never leave a blank space. The night before, stop revising early. Arrive early and settle your nerves before you start.

‍

In this guide, we'll cover command words, time-per-mark strategy, blank-answer mistakes, and what to do the night before and on exam day.

‍

Let's get straight into it now.

Key takeaways

• According to JCQ's summer 2026 results, 9.6% of UK A-level entries achieved an A* and 28.5% achieved an A* or A. Reaching an A* takes deep subject knowledge and technique that holds up on every paper.
• Command words signal the type of answer the examiner expects, while the mark value shows how much credit is available. Exam boards define command words differently, so check your specification and past mark schemes.
• Work out the time-per-mark rate for each paper by dividing its time by its total marks, then move on from any question that's eating into time you need for the rest.
• Never leave an answer blank. In Maths and the sciences, correct working often earns method marks, and on multi-part questions each part is marked separately.
• The night before your exam, stop active revision by 8pm, pack your equipment in a see-through pencil case as JCQ requires, and go to sleep by 10 or 11pm for a full eight hours before a 9am or 1:30pm session.
• On exam day, arrive 20 to 30 minutes early and try the 5-4-3-2-1 grounding technique (five things you see, four you touch, three you hear, two you smell, then one you taste or one slow breath) to bring your focus back to the room.

How to get an A* at A-level

Getting an A* at A-level comes down to consistency: scoring strongly across every paper in the subject, not excelling on one and dropping marks on another, since your grade is decided on your total raw mark across all papers combined.

‍

According to JCQ's summer 2026 results, 9.6% of UK A-level entries were awarded an A*. Overall, 28.5% achieved an A* or A. Closing the gap between the two takes deep subject knowledge and technique that holds up on every paper. 

‍

Your subject knowledge sets your ceiling. Exam technique, meaning command words, time management, and structure, is what determines whether you reach it on the day. That's the half of the equation this guide covers.

Command words: what examiners actually want

Every question in your A-level paper is built around a command word. That word tells you what type of answer the examiner expects, so knowing the topic isn't enough on its own. 

‍

Here's what each command word is asking you to do, with a sample question and answer for each:

Each answer earns its marks by matching the command word, not by writing more. Learning to read a command word correctly is what separates a confident A-level answer from guesswork. The mark value tells you how much credit is available, and the mark scheme tells you what earns it.

‍

These definitions are a general guide. Each exam board defines its own command words. The same word can also ask for more in one subject than another.

Time-per-mark: budgeting your exam

Before you write a single word, divide the time for that paper by its total marks. That gives you your time-per-mark rate, and it changes from paper to paper. Papers with reading time, source analysis or data questions usually give you more time per mark.

‍

Apply that rate to each question as you go. On a paper that works out at one minute per mark, a 12-mark question gets about 12 minutes, not however long feels right in the moment.

‍

If you're stuck, don't sit there burning your allocation. Write down what you do know, mark the question, and move on. Return to it once you've secured marks elsewhere. 

‍

This kind of exam discipline is one of those A-level tips that sounds obvious but rarely gets followed under pressure. A half-finished answer you return to still earns marks. A blank space from running out of time never does. 

Never leave a blank answer

Speaking of blank space, never leave a blank answer. It's the one guaranteed way to score zero.

‍

In Maths and the sciences, correct working often earns method marks even when your final answer is wrong. In essay subjects, a few relevant, developed points can still reach the lower mark bands.On multi-part questions, each part is marked separately, so attempt every one.

‍

A rushed bullet-point answer, or even an educated guess, can still pick up marks that a blank space simply cannot.

Structuring longer answers

Many longer answers are marked in levels, where structure and depth of argument count alongside content.

‍

Here are the steps to structure a longer answer before you start writing:

1. Underline the command word and note the mark value so you know how much depth is needed.
2. Jot a quick bullet-plan of 3 to 4 points in the margin before writing a single sentence.
3. Order your points so each one builds on the last and leads towards your judgement.
4. Write a brief judgement or conclusion at the end, especially for evaluate or discuss questions.
5. Check your plan against the mark value once more before moving to the next question.

Checking your work

Aim to leave the final five to ten minutes for a check pass, rather than reading back from the start. If you still have answers to finish, do that first. Check that you've answered every part of every question, especially multi-part questions where it's easy to miss a sub-section. 

‍

Re-read your calculations for arithmetic slips, and confirm your units are correct. Check that your longer answers actually addressed the command word used, not just the general topic. This pass catches marks a full re-read usually misses.

The night before your exam

At this point, you've done everything you could to prepare, and what happens the night before matters more than any last-minute revision, since sleep, preparation, and a calm evening protect your focus far more reliably than squeezing in extra content ever will.

‍

Here's how to spend the evening so you walk in ready, not wrecked:

1. Stop active revision by around 7 or 8pm, since new information learned late rarely sticks and often crowds out what you already know.
2. Pack your equipment in a see-through pencil case, which JCQ's exam rules require in every exam room: black pens, a pencil, ruler, eraser, and a calculator if your paper allows one, with its memory cleared. 
3. Bring any ID or candidate number your centre asks for, plus a clear bottle of water with any label removed. 
4. Lay out your clothes for the morning, ideally something comfortable you can layer, since exam halls can run warm or cold depending on the room.
5. Leave your phone, earbuds and any watch at home, or hand them in as your centre instructs. Simply having one on you breaks the rules, even if you never use it. 
6. Go to sleep by 10 or 11pm at the latest, to get a full eight hours before a 9am morning session or a 1:30pm afternoon one.

Exam-day morning and managing nerves

Wake up early enough to avoid rushing, ideally with time to spare before you need to leave. A rushed morning adds stress before you've even opened the exam paper. Eat a proper breakfast, porridge is a solid choice, since it releases energy slowly and keeps your blood sugar steady rather than spiking and crashing before your exam ends.

‍

Arrive at the exam centre 20 to 30 minutes before your session starts. This gives you time to find your seat, settle in, and avoid the panic of a last-minute dash.

‍

If nerves spike once you're seated, try the 5-4-3-2-1 grounding technique. Name five things you can see, four you can touch, three you can hear and two you can smell. Finish with one thing you can taste, or one slow breath. It helps pull your focus away from anxious thoughts and back to the room. That's exactly where you need to be when the invigilator says to begin. 

‍

Between a calm night before and a steady morning routine, you've covered the two windows that decide how settled you feel walking into the exam hall. For a broader look at managing your mindset across the whole exam period, not just exam day itself, our guide on How to Prepare For Exams is worth a read. 

How many hours a week should you study?

According to research by Barbarick and Ippolito, published in the Journal of Natural Resources and Life Sciences Education, you'd need 4.5 to 6.4 hours of study per exam to score around 90%. 

‍

Although, this was based on US undergraduate students, not A-level students specifically, and measured per exam rather than per week, but the underlying pattern still applies: study time predicts performance, up to a point, after which extra hours stop making much difference.

What are the four hardest A-levels?

Further Mathematics, Physics, Chemistry, and Biology are consistently named the four hardest A-levels, based on Ofqual's inter-subject difficulty comparison, teacher surveys, and A* grade rates. 

‍

Further Mathematics tops Ofqual's comparison by a clear margin, driven by abstract algebra and advanced calculus. Physics and Chemistry demand similar mathematical precision, while Biology's difficulty comes more from content volume.

What if I don't know the answer to a question?

Never leave it blank. Write down what you do know, since examiners award method marks and partial credit even for incomplete or attempted answers.

How do I get an A* at A-level?

Consistency across every paper, not just excelling on one. Your grade is decided on your total raw mark across all papers combined, so technique holding up throughout matters as much as knowledge.

Conclusion: Technique is a skill you can train

Strong A-level exam preparation isn't about knowing more, it's about applying what you know under real exam conditions.

‍

Command words, time-per-mark budgeting, and never leaving a blank space all separate a grade you're capable of from the one you actually walk away with.

‍

The night before and the morning matter just as much as the content itself, and a calm, prepared mind performs better than a rushed, cramming one.
