Use the Questions by Topic to learn and practice each topic individually.

Once you feel reasonably comfortable with each topic, go through the practice exam papers under test conditions.

Mark your paper and track your progress by recording down your score.

Identify your mistakes and write down explanations for them (e.g. careless mistake, need more revision, ran out of time).

For the questions which still need more practice, identify the topic and revisit the Questionbank for extra practice.
