Scared about DT

Hello friends,please suggest how to study for Direct Tax.I am very weak in this subject.Even in IPCC I passed mainly bcoz of Indirect Tax portion

I am not comfortable about self study so please suggest whose online lectures are the best(if you have attended them).My options are CA Farooq Haque,CA Prasad Bhandari and CA Vivek Goel

Also tell whether I can prepare from summary book of VG/Manoharan.I wont be able to do all the modules as time is limited
