The short version
- Marks are never spread evenly across an exam, so your study time should not be either.
- Find how much each topic is worth, then rank the topics from heaviest to lightest.
- A few topics usually carry most of the marks. Back those first and hardest.
- Give the light topics a quick, clean pass, not hours.
- If a subject spreads its marks evenly, switch to steady coverage instead.
The mistake almost everyone makes
Most people study a subject front to back and give each topic about the same time. It feels fair and organised. It is also the slowest way to prepare, because it treats a topic worth a quarter of the exam the same as one worth a twentieth.
Exams are not built that way. The marks are lumpy. A handful of topics usually carry most of them, and the rest are split across what is left. Once you can see that shape, you can aim your hours where they pay off, and stop feeling like you have to know everything equally well.
This one habit, studying by the weighting, sits behind every subject guide we write. Here is how to do it for any exam.
Step 1: find the weighting
Start with how much each topic is worth. Most subjects tell you. The subject outline usually lists each module and its share of the exam. If it does not give exact numbers, you can still work out the order.
No published weightings? Estimate them
If your subject does not print exact figures, count the pages or the learning objectives under each topic. The biggest sections are almost always the heaviest in the exam. You do not need precise numbers. You need the order of importance.
Step 2: rank the topics and see the shape
Line the topics up from heaviest to lightest and a pattern appears. Two or three anchors carry a big share, a middle band sits under them, and a few light topics round it out.
How exam marks tend to cluster (an example, not a real subject)
Illustrative only. Every subject differs. This shows the shape of a typical weighting, not the marks for any specific exam.
In this example, the top two topics are nearly half the exam between them. That is the shape you are looking for. Your plan almost writes itself once you can see it.
Step 3: spend time by weight, heaviest first
Put your best, freshest hours on the two or three anchors. Get them from shaky to automatic before you touch the light topics. This is the opposite of the usual front-to-back approach, and it is far more effective.
Worked example
Say two topics are worth 25 and 20 per cent. Together that is nearly half the exam. Get those two solid and you walk in already ahead, whatever happens with the rest. So that is exactly where your first and best hours belong.
Step 4: do not skip the small topics
Weighting your time is not the same as skipping topics. Light topics are still marks, and some exams expect competence across the board. Give them a clean, quick pass late in your preparation. The point is proportion, not gambling.
Exam trap
Read your subject before you commit to this. Some exams spread their marks evenly on purpose, or test the whole process in order. If the weighting is flat, the method flips to steady, even coverage, because there is no anchor to lean on. Back the heavy topics when there are heavy topics, and cover everything when there are not.
Why this works
Three reasons this beats even study time. The last stretch of a small topic costs the same hours as the first, most valuable stretch of a big one, so even time quietly wastes your best hours. The heavy topics are usually the ones the exam cannot avoid testing, so time there is rarely wasted. And getting the anchors solid early takes the pressure off, because you know the bulk of the marks are already covered.
Marks are never spread evenly, so your time should not be either. Find the few topics that carry most of them, and back those first.

Questions people ask
- What if my subject does not publish weightings?
- Estimate them. Count the pages or the learning objectives under each topic, and use the length of each section as a proxy. The order of importance matters far more than exact numbers.
- Does this mean I can skip the small topics?
- No. You are weighting your time, not gambling. Give the light topics a quick, clean pass so you can pick up their marks. Skipping them is a different, riskier thing.
- How do I know which topics are the anchors?
- They are the ones with the highest weighting, and usually the ones the exam tests every time. Rank the topics and the anchors are the two or three at the top.
- Is it risky to study unevenly?
- The real risk runs the other way. Spreading your time evenly leaves you under-prepared on the topics that decide your result, while over-prepared on ones worth very little.
- What if the marks are spread evenly across my subject?
- Then even coverage is the right call. Some subjects are built that way, or test a process in order. Read the weighting first, and match your plan to it.
We have already done this for every subject
Each of our subject guides shows exactly where the marks sit, and every pack condenses the heavy topics first, so your time goes on the topics that carry your result.
