Urgent query ca final nov 15 exams

Dear CCIties

I am having the DT & IDT both are padhuka publications which were purchased for May 2015. Whether it is sufficient for the Nov 15 exams or I need to purchase the new books.

for DT can i use the summary book of T.N Manoharan and PM instead of DT by padhukas.

For ISCA - I have Dinesh Madan book which was published during nov 14 the content headings are as same as the institute material. Would I need to buy new book or I can continue with the existing book.

awaiting the reply
