Hey,
Well,there is no special secret to score more than 90 percent in 12th boards. You just need to believe in yourself that you can score well. Just work hard and read your NCERT thoroughly. For Chemistry,make sure you are thorough with NCERT. Solve the solved and unsolved examples of the book. For Physics,be thorough with the derivations present in NCERT. You could also study from Dinesh or Pradeep. For Mathematics,solve NCERT and other books as recommended by your teachers.
Hope this helps.
Good luck.

hey dear, the answer to this is hard work and consistency,make it very clear for the rest of the year.Make a routine and strategy plan for your study and give time to yourself even.Be discipline towards this and you will achive what you want,all the best.

Scoring 90%+ in 12th boards is pretty easy if you know how to do smart work. Getting good marks simply depends on whether you know which topics are important or not. For getting this ability you should scan through the past year papers as some of the questions or the concepts in them repeat frequently and this will help you to identify the most scoring topics and after you have mastered them you should go through all the other topics in the decreasing order of their importance. This should help unless CBSE decides to drastically vary the difficulty level. Hope this helps.
