for ISCA you can either go for Dinesh Madan's book or you can take Munish Valecha's book.
Madan Sir's book is popular for its Simple language.
But i personally prefer Valecha's book, it have Lots of Mnemonics you can learn ISCA with them easily.
for IDT i dont know very good book out in the market for self study. Although you may go for Deepak Gupta Sir or Raj Kumar Sir.
