When should you start exam preparation?

Your exam is suddenly close, your notes are everywhere, and every topic seems urgent. To focus on replacing last-minute cramming, work backwards from exam day, give weak topics more attention, and spread practice across short sessions. You do not need a perfect timetable; you need a realistic first week.
Start once you know the exam date and topics. If you have several weeks, use them: an earlier start gives you room to revisit difficult material and recover from interruptions. There is no universal number of weeks that guarantees readiness. Your starting point, the amount of material and your available time all matter.
Put the exam date on a calendar, then mark commitments you cannot move. Count the study slots you can genuinely protect, not the hours you wish you had. Work backwards to reserve later sessions for mixed practice, checking recurring mistakes and revisiting material that still feels uncertain.
For an exam six weeks away, you might spend the first week checking your starting point, the middle weeks learning and practising, and the final week reviewing errors. Keep testing yourself throughout. If the date already feels frighteningly close, these ways to prepare for exams without feeling overwhelmed can help you turn the remaining time into specific actions rather than an impossible catch-up mission.
Prioritise weak topics using evidence

A topic list tells you what could appear, but it does not tell you where your time will help most. Before building your timetable, try a few representative questions from each main area without your notes. This is a starting check, not a verdict on your ability.
Sort topics into three practical groups: you can answer independently, you can answer with prompts, or you cannot yet explain the approach. Add a short note about the difficulty. “Forgot the key term” calls for a different session from “Could not choose a method.”
Next, check the exam guidance for how topics are assessed. Give more attention to material that is both shaky and important, including foundations needed elsewhere. Do not spend your whole week polishing a comfortable topic just because completing its questions feels satisfying.
For example, you might remember definitions accurately but struggle to use them in longer answers. Your priority is then answering and checking a longer question, not rewriting the definitions in a prettier notebook. Keep a smaller amount of time for stronger material so it stays accessible.
Review these priorities weekly. When you can answer several varied questions independently and explain your choices, reduce that topic’s share of the plan. Move attention towards the next clear gap, rather than treating your original timetable as permanent.
Build short sessions into a usable weekly plan
A weekly plan needs more than a subject name beside each day. Include a time, a realistic duration, one small target, the materials you need and a way to check the result. “Tuesday after dinner: practise two explanation questions and check the marking guidance” is something you can actually begin.
Start with sessions of around twenty to thirty minutes if getting started is your main obstacle. That is a practical starting point, not a rule about how long anyone can concentrate. Choose a length you can repeat, with a short break between sessions when you schedule more than one.
Inside a session, briefly recall what you know without looking. Then answer questions or work through the part you do not understand. Finish by checking your work and recording the next step. Reading can help you repair a gap, but it should lead back to an attempt without notes.
For a twenty-five-minute session, you could spend five minutes recalling key ideas, fifteen answering questions and five checking mistakes. If the questions take longer, use fewer; the aim is useful feedback, not racing through a quota.
Across the week, include priority topics, a return to earlier material, mixed practice and one spare slot. Avoid common study mistakes such as treating hours spent rereading as proof that you can answer independently.
A sample revision week you can adapt
This example uses short sessions for an exam several weeks away. Replace the topic descriptions with your own, and move the times around your actual commitments. Each session produces something you can check rather than just a tick beside “revision.”
Monday, twenty-five minutes: Try four questions on your weakest important topic without notes. Check your answers and identify the main problem. Write a precise next step, such as practising how to select evidence for an explanation.
Tuesday, twenty-five minutes: Review one worked example addressing Monday’s problem. Close it, answer two similar questions independently, and explain why your answers meet the question’s requirements.
Wednesday: Keep this evening free as a buffer. If nothing needs moving, take the break. A sustainable week does not need a study session in every available space.
Thursday, twenty-five minutes: Return to Monday’s topic with different questions. Then briefly recall a stronger topic from memory. Record whether the original mistake has improved or still needs attention.
Friday, twenty minutes: Work on your second-priority topic. Use your notes only after an initial attempt, then retry the difficult part without them.
Saturday, thirty-five minutes: Complete a small mixed practice set and check it carefully. Note errors caused by missing knowledge separately from errors caused by misreading.
Sunday, ten minutes: Review those notes, choose next week’s priorities and book your sessions. Keep unfinished work only if it still deserves the time.
Recover missed sessions without abandoning the plan
Missing one session does not mean the routine has failed. The bigger risk is deciding you must now complete everything you missed before you can restart. That turns a manageable plan into a growing debt and makes the next session harder to face.
When you miss a slot, first check whether its task still matters. If it addresses a major gap, move it into your buffer or replace a lower-priority task. If later practice shows you already understand it, shorten it or remove it. Your plan should respond to evidence, not demand repayment.
Suppose you miss Tuesday’s session because another commitment runs late. You could move the worked-example practice to Wednesday’s buffer. If Wednesday is unavailable too, use Thursday for that task and postpone the brief review of stronger material. Do not automatically double Thursday’s workload.
On a difficult day, use a minimum session: answer one question, check it and write down what to revisit. This keeps the next step clear, but it is not a requirement to study when you are unwell or need rest.
If you repeatedly miss the same slot, change the arrangement. Try a different time, a shorter session or materials prepared in advance. At your weekly review, plan from the time you actually used successfully, rather than repeating an optimistic schedule that never fits.
Choose today’s task and book your next three sessions
Do not finish by planning every remaining day in detail. Start with one task small enough to do today. Pick a topic you find difficult, open a relevant practice question and attempt it without notes. Your first useful result is discovering what needs work, not getting everything right.
Give this first attempt ten minutes. Check the answer, name the gap and leave yourself a specific instruction. “Review how to structure the explanation, then retry the question” is more useful than “Do more revision.” Put the necessary materials together so starting again takes less effort.
Now schedule your next three sessions with actual dates and times. For example, book tomorrow after dinner to repair today’s gap, a session two days later to answer fresh questions on it, and a weekend slot for mixed practice. Give each an achievable length and write down what you will check at the end.
Before you stop, identify a backup slot in case one session moves. You now have a task for today, three appointments and a recovery option: enough structure to begin without building an elaborate timetable.

Frequently asked questions
Start now, but narrow the plan. Use a short practice check to identify important gaps, prioritise those topics and leave time to review mistakes. Avoid trying to compress an ideal multiweek timetable into a few days.
Include realistic study times, specific topic targets, practice questions, checking time, a return to earlier material and a buffer for interruptions. End the week by adjusting priorities using what your practice revealed.
No. Move essential work into a buffer or replace a less important task. Shorten or remove work that no longer addresses a gap, and restart with a manageable session rather than doubling your workload.
Try fresh questions without notes and check your reasoning as well as your final answers. Look for fewer repeated mistakes and a growing ability to explain your approach. Familiar-looking notes alone are not a reliable check.
