hi dear..i m in class 11th..its nt so that studies are very difficult.the thing is that we need to concentrate more..and stdy hard!its quite interesting.dont worry.and ya u can try HCV for physics .It ll help u to clear ur concepts..

ALL THE BEST !!

• acctually its not to much tough ....if u'll give ur continious nd proper hours for study nd also concentratee on many little points then its to easy for u to be a gud itian ranker..in physics if u'll use direct hcv then it create some problem to ..u ..u should firstly make ur basic strong then use hcv ...then it wud be too much easy 4 u...nd in chemistry...ncert volumes r the best for ..but for numericals use r.c.m..nd in math's firstlly clear ur derivation part mean in basic structure from r.d sharma then use a.d das gupta...al d best 4 u prepration..................................tc 

ya i also agree wid ankit sir,hcv is best wen ur concepts r clear...it has very good questions!!after clearing of concepts den refer HCV...

all d best :)
