Idt/dt/audit/law coaching

Hello Friends,

Please help me out in choosing between a few options available to me as per my pocket:

1) DT- Is Satish Mangal sir good at teaching DT. Although VG sir's knowledge is unquestionable but still Is Satish Mangal sir good from the exam point of view??? Any other good option available other than him???

2) IDT- which one is the best one amongst these: Manoj Batra Sir or Vinod Parakh Jain Sir??? I have heard that in group 2, IDT is one of the most scoring subject. 70 marks is chasable in it. Any other better option available who can help me in achieving this feat???

3) Audit- Kamal Garg sir or Dharmendra madan sir or RK Rastogi sir or Vinod Parakh Jain sir??? Which one is the best option to make a step forward???

4) Law- Any good teacher if in your knowledge, can advice me except Munish Bhandari Sir???

Please solve my query friends.

Your few precious minutes can save one's future going in wrong hands.

Thanks in Advance.
