Dude .... i have gone through the same phase .. ..

 

See let me suggest u some ways to get out of this problem ..

 

First of all u shud decide what is ur priority ... I decided that my priority is JEE and if school suffers then let it be ... but to tell u my school did not suffered either .... i got 93% is boards which is decent enough i gues ...

 

welll let me tell u the way i used to manage .. i made a point that i will go to my school regularly .... the benefit was that even if I was not giving time to school studies I always knew what all is going on in the school n i was able to wrap things when school exams came near ...

 

Another point is that since u are in CBSE i can make this point even more strongly ... the concepts reamain the same whether it is JEE preparation or the school stuff ... most of the school course say 60% atleast gets covered if u properly prepare for JEE ... so i never faced much problem coping with school even if it is hard and at times maked u feel frustrated .. but then dude remember this is how life is .. TOUGH ... but then two years u work hard and then u have a gr8 career ahead

 

Cheers .... more doubts feel free to reply back
