Dear karishma ;
Plz dnt gi through classes of yashvant mangal.
Prof. Rajesh tayalnsir notes is suffice to get more than 80 marks.
I read twice of tayal sir notes and got 74 marks in idt without any classes.
Karishma buy xerox or tayal sir notes in any xerox vala shop....and no need to take coaching in idt..it just waste of time and money and its better to u learn by ur self this subject .
Mail me if u want further help hemang_005 @ yahoo.co.in
