chill man

focus on 10  iit is going nowhere.......

start prep from 11

but one thing i can say just start the prep for 10 too the way iit is prep

try to get into basics of everything

shallow knowledge may help you in 10 but not in iit

in maths start doing more and more practice

don't waste time on useless topics. etc etc

 

wishing you a lots of success

for 10 and iit

rate if you like the ans
