Hi Ishan

Scoring above 95 in 12th boards is fairly staright forward. Since you haven't mentioned which stream you have taken, I will give a general answer. There is a very simple trick to acing board exams- be thorough with the NCERT. Many students actually spend a lot of time studying different reference books, which not only diverts attention, but also wastes time. However, once you are thorough with the NCERT, reference books are a good next step. Solving past year papers a month before can really help in consolidating your preparation.
