Tips:
Practice, practice, practice!!! Do topic questions after each completed topic, mark it and notice where your weak points are and focus on them more. Towards the exam (3-4 months) just do past papers. Print the past paper, revise the entire syllabus beforehand and them treat the past paper like an actual exam. Mark it, circle the questions you got wrong, and learn how to answer it. Try to do 3 biology past papers each week assuming that you are taking 3 subjects total. That way you'll be revising 3 times a week and know the syllabus like the back of your hand. For biology along with theory its your writing style that matters as well, so practice improving it. Try to make your answers clear and concise unless asked to explain, describe or elaborate. So those questions that you circled previously in the past papers and topic questions, revise them before the exam and try them again without looking at the answer beforehand.
