By studying 45 minutes at a time.
By going over your notes as soon as you get them
Try to understand the work and explain it to yourself what you know
If you have say 3 question to write on look at them and think which to answer
Get 3 sheets of paper starting writing what you know about most do not try writing everything thing. stop
take the next sheet of paper write what you know do not try writing all stop
take the next sheet of paper write what you know. do not write all you know
stop go back to question one and put iin what you miss out that you think is important by now more facts will keep coming
Do the same for the other two questions. If your paper can be answered in tabulated form try using it as best and as skilfully as you can. you may lose points for flow but you gain it for facts.
The best trick of all you have to answered the 3 questions you were required to do.as best as possible
If a question value 30 marks you cannot get more than 30 why not get 25 on each instead of trying to get 30 on the first and time runs out on you that you cannot answer the last or you get only 8 on the last.
That is how a did well on my exams Got the best marks using that method.Ones the brain starts facts begins to flow you may have to do all 3 question at ones when the facts starts start flowing It can be so much fun try it. Never answer 3 written question on the same sheet of paper if you can help it
Do not try to cram the night before.Always look over your notes as you get them.try to visual the pages the teachers voice and make additional notes. Study with a friend.. Go in the room and stop worry just write what you know be calm. And if it is applicable follow the rules above
