Study practice

Turn a past paper into a revision plan

Use a worked marking log to choose your next study session and check whether you can solve a problem independently.

What you’ll learn

  • Separate knowledge gaps from mistakes in execution.
  • Choose a specific practice task and check it with a fresh question.

Before you start: Have your current syllabus, an authorized past paper and a blank notebook ready.

In this guide 6 sections

A past paper is most useful when it tells you what to work on next. Simply collecting papers, highlighting solutions or recognizing a familiar question can hide a gap in your method. Use the process below to turn one authorized paper into a short, specific revision plan.

Check the paper before studying from it

Match the institution, program, subject code, curriculum and year to your course. A similarly named subject can have a different scope. Compare the topics with your current syllabus, and mark any question that is outside it. Old papers show previous questions; they do not guarantee future questions or current marks distributions.

Record where the paper came from and use material you are allowed to access. If the scan is incomplete or a diagram is unreadable, choose another question instead of guessing missing data. Keep solutions closed during the first attempt.

Make one honest attempt

Choose a manageable group of questions. For a timed practice, use your actual exam's instructions. As a planning example, a 120-minute, 60-mark paper gives an average of two minutes per mark before reserving checking time. A ten-mark question might receive about 20 minutes, but the real allocation depends on its demands and the paper's rules.

Write the method and intermediate steps, not only the final answer. When you get stuck, write exactly where: “I can identify the forces but cannot choose the sign convention” is more useful than “I do not understand mechanics.” Stop the timer before looking at help and label any work completed with help.

Build an error log you can act on

The table below is an illustrative log, not a real student's record or an official marking scheme. Each next action targets one cause rather than asking for a whole chapter to be reread.

From an observed mistake to a next action
QuestionWhat happenedNext action
DC circuitUsed the source voltage across every resistorMark common junctions; solve a new series–parallel example
Loop outputIncluded the stopping value in a rangeTrace three small boundary cases by hand
Short explanationNamed a principle without applying itWrite a claim, explain why, then connect it to the question
CalculationMethod correct; units missingAnnotate units on every line of the next attempt

Classify the mistake as a concept gap, procedure gap, reading mistake or execution mistake. These categories are a practical organizer, not a score. A concept gap needs explanation and a new example; an execution mistake may need a deliberate checking habit.

Plan the next session around one change

Example: a 40-minute session for the circuit mistake

  1. Spend 5 minutes drawing and naming the junctions.
  2. Use 10 minutes to work through one explained example.
  3. Spend 15 minutes solving a different question with the explanation closed.
  4. Use 10 minutes to compare steps and record what you can now do independently.

Adjust these times to your schedule. The key decision is the independent second question. Repeating the same answer from memory does not show whether you can apply the method to changed numbers or a different diagram.

Try choosing a next action

You recognize every formula in a worked solution, but cannot choose one when the question is presented alone. Should your next session focus on copying the solution or deciding which conditions make each formula applicable?

Compare with a suggested approach

Work on choosing the method. For each question, list the known values, the unknown, and the conditions needed for the formula. Explain why an alternative formula does not fit. Then attempt a new question without seeing its solution. Copying may help notation practice, but it does not directly test the selection step that caused the difficulty.

Decide what “ready” means for this topic

Before moving on, try to explain the method in your own words, solve an unfamiliar example without hints, and check the answer. If one of these fails, record a smaller next action. Keep difficult topics in your schedule instead of relying only on questions you already enjoy.

Use an official marking scheme or your teacher's guidance where available. If a solution and your working disagree, compare assumptions and units before treating either answer as authoritative. Ask for clarification with your attempt attached so the specific gap is visible.

For a concrete next exercise, try the worked DC circuit or the loop tracing guide, then find a matching topic in your syllabus.
