Short term dt strategy nov 15

please guide me as to which book should i refer for DT for upcoming nov 15 exams?

i have not taken any coaching classes and my articleship was mainly focused on audit work.

i dont intend to practice in taxation field after completing my CA. so for the sake of clearing the exams i have to clear DT.

I have both VG sir's full modules and TN sir's full book at my disposal from my friend.

i read a few topics from manoharan and a few from VG . VG is a more simple book according to me.

but manoharan is a to the point book and i am not getting confidence after reading TN sir's book.

on the other hand VG is 1800+ pages. and time is not enough

please can anyone help me crack DT . i would be the most happiest person even if i score 50 in DT.
