Dear Student,

Definitely yes, nothing is impossible. Proper planning, learning, hardwork and dedication will help you to score good marks in you Finals. You have no choice but to remember the NCERT. Read the textbook. Make notes while doing this. Every year, CBSE releases sample paper for Class 10 and Class 12 before the board exams. With the help of CBSE sample papers, students get the complete idea about the latest CBSE examination pattern & the level of questions which are expected in the CBSE board exams. Last 3 months plays an important role in deciding the final percentage of your board examination, so use these last 3 months in a very intelligent and logical way, by creating a proper time management and giving proper time to every subject.

I hope this helps, wish you all the best!
