no.....if suppose i have half yearly exams tomorrow and im coming from iit coaching now at 9 pm.....how will i read 2 volumes of phy or chem book within the available time........advise me now itself......b coz i have to decide whether to join iitcoaching or not..........!!please reply fast....!!

First of all aisi situation kabhi nahi aayegi because you would have read more than half of the stuff that will come in your half yearly in your coaching already. Sirf kuch topic revise karne padenge which will not take much time. Moreover,Halfyearly me pass hona kaafi hai. Infact, agar entrance exams me good performance deni hai to you should join some good coaching.

Plz. approve the answer if u like it. 

if You have been truly preparing for IIT the you should have difinitely done NCERT much before half yearlys that are held in mid Sep. You may revise conceptual problems from any private books do all derivations from NCERT back exercises

These will help you to score good marks

Thanks

u can my boy u can join fr sure
