This is from a revision book i have:
1. be physically and mentally prepared ie. make sure you have adequate sleep, relaxtion, exercise and a blanced diet/
Know when to give yourself a break and when to stop. To be able to maintain your efficiency, you must take regular breaks in your study routine
2.Develop a positive attitude about your abilities- your marks will reflect the amount of work and preparation you put in to enhance your potential.
3.Be methodical in your preparation. Plan a revision timetable, Go through your chapter summaries, complete exercises on each topic and other topics that link to that topic.
4.Do trial exams. These will show you the questions to expect and how to write your answers. Make the trial exam as realistic as you can( conditions, time, materials etc). Dont overdo it, this can cause burnout.
5.Use trial papers, SACs and comments from your teacher to pinpoint weaknesses, and to improve these areas.
