The Priority Filter

From Module 1

The specification tells you what can come up

Every exam has a specification (sometimes called a syllabus). It lists every topic that could appear in the exam. Nothing outside the specification will be tested.

If you have not looked at your specification, you are revising blind.

Not all topics deserve equal time

In Module 1 you learnt the triage system: green (know it), amber (nearly there) and red (do not know). As a starting point, this is a sensible split for most students:

Amber topics get most of your time because you already have schemas for them (remember the basket from Module 1). Your brain can build on what it partly knows.

Red topics only get time if they appear frequently in past papers. A red topic that rarely comes up is not worth your limited time.

Green topics just need a quick retrieval check to make sure they are still solid. Do not waste hours perfecting what you already know.

Four steps to a focused revision list

Sort these topics by priority

Module 1 already gave you the headline rule: amber is your priority because that is where your time gives the best return, and red is "be strategic — focus on amber". Module 2 adds the second variable that decides where each topic actually lands.

For every topic, do two checks and put them together:

1. Confidence level. How well do you know it? Green (know it well), amber (nearly there), red (do not know it yet).
2. Exam frequency. How often does it appear in past papers? Every year, most years, some years or rarely.

Combine the two to set priority: H (high), M (medium) or L (low).

Two worked examples

The first confirms the Module 1 rule. The second is the exception that frequency creates.

And green? Always a quick check, regardless of frequency. You already know it — do not let confidence trick you into spending time there.

Now you try — Biology

Read the quote (that gives you the colour) and the frequency. Then tap H, M or L.

Maths and other problem-solving subjects

In subjects like maths, most topics appear every year. So frequency is not the deciding factor — the topics are all "frequent". Instead, swap frequency for how many marks the topic carries.

The rest is the same: confidence first, then mark weighting, then combine. A 5-mark amber topic is worth far more of your time than a 1-mark green topic.

Two approaches to the same week

Past papers are not just for practice

Most students save past papers for the end. That is a mistake. Past papers should be your starting point.

Build your focused revision list

List your priority topics for one subject. Aim for somewhere between 5 and 15 – fewer if you're short on time or shaky across the whole subject, more if you have time to revise each one properly. There is no magic number. The point is to focus on what gives you the most marks for the time you have.
