Sir i want to know is pradeep good for all types of chemistry in 11 for iit pteparation . Is it good for concept building . If you have any good book in mind which can cover all types of chemistry then please suggest. I am also looking for op tandon which one is good

@ anushka 
There are many books avaliable in market , choose the one which will be best according to your level . and u must have to cover that book throughly . 
remember to cover any single book completely , 
ncert is sufficient for inorganic , for organic , take morrision and boyd , thats the best for jee level .
for physical , o.p tandon is good . otherwise u can take out any books of arihant publication . 
dnt go for pradeep , it can be satisfied upto jee mains , but not for jee advanced .. 
HOPE IT HELPS
