Dear Jaydrath
Try  to find out your mistakes in the tests. find out your area of  weaknesses and work on them. You are presently in 11th. you have enough  time for preparation dont worry about time. Work hard on weak areas.  give sufficient time to those areas.Try to understand the concepts.
In  the exam hall after getting the paper first read the whole paper  quickly. It will give you a rough idea about the questions to be  attempted.
Dont try to do the complete paper  rather try to do the questions correctly in which you are confident,  this will reduce negative marking. make some targets that I have to  these number of questions in this much time. Students generally try to  attempt the whole paper and make mistakes in hastle.
Do only those questions in first  attempt in which you are very much sure and which are not lengthy.  attempt these questions in the 2nd attempt if time permits.
All the best.
