The first advice is to maintain a diary.
See, If you are reading a topic today then make a schedule or a reminder in your diary that exactly next week on the 8th day you must revise that topic what you have learned past week. You can use a digital calendar like google calendar to do this but then, I suggest you to maintain a book to do so. And again plan for a schedule to read the same topic after a week. As you are reading it every week it stays fresh in your mind and when you feel you are comfortable with that topic you can increase the gap from one week to two weeks or as you wish.
What is the best time to revise for exams?
As we all know, our human brain is divided into two parts(left brain and right brain). Generally when we read anything it goes directly into our left brain and we can call it as the RAM. And after that when we sleep the information from the left brain goes into our right brain and it is permanently stored there.(which requires constant reading to memorize it).
So it’s clear that the best time to revise or prepare for exams is before you go to bed. let’s say if you are sleeping at 10 pm. It’s better you read from 9 pm- 10 pm. And right after you read, just go to bed without doing anything like watching TV.
How to revise for Final Exam?
If you are starting your preparation now and your exams are in two months, you need to make weekly sessions and work according to them. See, If a topic takes two hours to prepare at the 1st try. Then it takes less than two hours at the second try. So after a few sessions of revision you will be in a position to revise that topic within few minutes.
This practice of revising topic in a regular time gap will help a lot like you may not able to concentrate for more than 2-3 hours sitting in front of books but you can make out one hour for every session you plan to revise and learn accordingly. And as you go on planning the schedules you can increase the time that you allocate for revision.
The main secret for success in the exam is not how much you learn -it is how well you have prepared your notes and how much of those notes is in your brain, how much can you recollect in your exam. At last your presentation matters.
