Hello!

Stating this statement is a bad sign. Last 2months preparation might help you score more than 70% but 85% is a difficult thing. For Physics use SL Arora they have clear idea on topics and from board perspectives that particular book is so handy make sure you focus on all the things starting from conceptual readings to question and answer part, this book could be a help for you for 2 months preparation. For chemistry have your book in finger tips that is more than enough but it might take more than 2 months. For maths first school books then question banks, even for mathematics it will take more than 2 months.

Work hard on tiring situations take short breaks for efficient reading. Rather than memorizing learn the concepts. They might turn more useful in future.

If you are a CBSE student have your NCERT mathematics and NCERT chemistry in finger tips to score 85% and for physics SL Arora. This will help you score even more than 85%.

ALL THE BEST. Hope the answer was helpful.

Thank You

Hi

Getting a score of 85% in board examination is not that difficult , what all required is perseverance ,hard work and honesty for your preparation, and don't worry with dedicated  study you can definitely prepare in 2 months

Follow the below tips:-

*First of all go through NCERT and don't ignore it at all most of the questions in board examination are based on NCERT, you can take the help of reference books to understand the difficult  topics and have better understanding  but major focus should be on NCERT

*make a routine and religiously follow it, it will help you to avoid wastage of time and study in a systematic manner

*For biology, you should read the chapter first then understand the biological processes and then learn them my heart and also learn the important examples.

*For chemistry go through all the solved examples and intext and exercise questions of NCERT , in organic chemistry focus more on name reactions there are two questions from name reaction each year in board examination and many questions are based on them directly

*For physics,  practice  all the derivations from time to time as there are chances of forgetting them if you don't revise them, derivations are very often asked in your board exam, go through solved examples and then go for unsolved numericals.

*Make short notes of important concepts and formulas for each chapter

*Go through previous 10 year board examination question papers as concepts are often repeated in board exam so it will be of great help in your preparation

*Once you are done with your complete board examination syllabus go through at least 3-5 mock test papers in each subject
