Which book to choose to practice practical questions?

use only practice manual for practical problems. if u analyse may 15 or nov 14 paper u can easily find out that, the adjustments asked in practical questions in DT are taken from various practical problems solved in PM only. same problem may not repeate but adjustments are repeated from PM.

By the way please tell me how is VG sir's summary module. Does it contain deduction provisions along with the deduction amount and all other concepts. overall how is the  book? I purchased T.N Manoharan's summary book, but its really a waste product, nothing given except heading and section number.

Please give ur reply on VG sir summary module.

I used practice manual in my previous attempts but didnt found that helpful to be honest. So I have purchased Bangar this time. Though more or less questions would be the same as PM.

I find VG Sir's summary book pretty helpful and to the point specially for last time revision but cant compare with other books since haven't used them. And yes as far as deductions are concerned they are explained really well.
