Final - DT guidance needed

Hey..

I have yet to start DT. I am very confused as to how to prepare for DT especially when this Nov's paper was so analytical.

I was considering BB sir's Fast-track PD classes, but then that won't be in dept. And I wanted to attend VG sir's classes but it's not available anywhere near my city.

Please give your suggestions/experiences on how to proceed with the subject. Class, books, anything..

Please do reply! Thanks a lot!
