1. Always revise what Sir has taught in class. The more you revise the  more  u will grasp. And this semester I am more confident on the topics  that I had revised than the one I neglected. So don't  forget to revise  what you learnt in class and do it within 24hours of the class!
 2. Out of the seven days a week always set one day for revision. This is  the day u will revise all that you have learnt in that week. This is important  as this will classify all the information you were collecting all week and will  give you a proper broad perspective of things you have learnt.
 3. revision is not only of the theory but also of all the numericals. Don't  neglect them. Only seeing won't do. Do it on paper. You are not here to save  paper so do it on paper and with pen just seeing it won't do any good.
 4. And always be at par with the things that are going on in class. That is  don't lag behind on what the faculty in class is doing. Stay with him. If you  missed a topic, work hard give some extra effort and study along with him. This  helps tremendously as you will see in the end of the semester you won't have to  run fast to cover the topics.
 5. Keep a log book of the things you have learned or the topics that you  have studied and covered so that  you can revise it latter by seeing that  log. This also helps in boosting you confidence to see all the topics you have  covered at one place. So maintain it. Its sometimes boring but  very useful  tool of motivation and revision.
 6. And above all stay focussed. I read somewhere and it applies her too.  Passion can motivate you towards your goal, its only hard work that will yield  it. So work hard. There's no substitute to it.
