Dear Student
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 do 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 rest of the questions in the 2nd attempt if time permits.
Mark the questions in the first attempt which you feel that you can do this but it will take time. then do these marked questions in 2nd attempt if time permits
Conclusion is do less questions but do it correctly.
 
All the best.
