Final DT and ISCA

Hi All,

Can any 1 tell me which ref book is better for DT?

Paduka or Girish Ahuja? and is it possible to finish Girish Ahuja before Nov exams if i start now?

What should i do to get good score in DT and ISCA?

I cleared my first attempt i.e may 10 and failed in DT at that time and in subsequent 2 attempts i failed in ISCA.Please suggest. 

Thanks in advance
