if your concepts are crystall clear then scoring 90 percent in cbse will not be a big deal .
you can easily get 90 percent , just balance the maths , for boards , start practicing sample paper from now , if u have not already .
and in everyday , do at least 1 sample paper from each subject , and analyse where u went wrong .
after that .
and simoultaneously do the revision from ncert of that perticular concept ,
currently focus only on board and not on jee ,
and after your exam will end , the rest 1-2 week focus fully on 11th revision .
for timetable , u need to prepare that of your own , as u knows which topic u need to spend most time and in which topic less ,
but maintain regular practice in maths and organic chemistry , else , they will make problem in board
ALL THE BEST ..
