Is H.C.Verma enough for IIT-JEE?

no because it is having more subjrctive questions

no

prefer cengage

no not at all 

if u do HCV then also do all previous iit questions n irodov

otherwise leave HCV and do cengage 

you can use cengage materials

prepare well

all the best

IT is more than enough if u solve it fully, cnge book are too big and will take lots of time, hc verma and irodov are more than enough, even the top batch students in kota solve only these two books and manage to get below AIR 200

but you should solve fully
