hey, chill, yaar!!

i understand , u must be getting tensed as the exams r nearing!! dont worry!!keep on putting effort till the last.....u work hard, u will achieve anything!!

6 hrs is enough!! i'm getting less than that!! in chem, ncert is more than enough!! for phy, first see whether u r able to solve the sample paper....if yes, then ncert is enough...if no,then get an extra book for more conceptuals and numericals!! maths- ncert and sample papers enough, i think!!

 

best of luck!! i'm sure you will get wat u want!!
