I am super confused as to which teacher I should take coaching from (except
Vinod Gupta sir- as the infrastructure is poor at my place) regarding DT and
IDT...
DT- Ranjeet Kunwar / Vikram Biyani / Jayesh Gupta?
IDT-Manoj Batra/ Rajkumar/ Jayesh Gupta?
 Who teaches the best in a short time?
Please help.Please do not suggest self study.
