Go through the exam paper and prioritise the topics according to the number of marks lost. Start by revising the topic with the most number of marks lost. Do correction without copying solution and do 1 or 2 more similar questions until can do correctly within time limit of 1.5 min/mark. If score 0 in that topic, practice 10 questions in that topic. After topical revision, do a practice paper under exam condition. Repeat the cycle of paper topical until can achieve your desired grade.
Focus on brushing up Calculus, Sequence and Series, Vectors and Complex Numbers. These four major modules account for more than 60% of marks in A level.
Can engage a good tutor to shorten the learning cycle.
