Dharmendra bhai has deep knowledge on almost subject included into UPSC/BPSC and one can get any solution from him without any partiality.

Dharmendra ( my friend) a very talented guy with hidden unerring ability to play only the smartest, the brighter and the most talented guy ever I met. He has huge experience of explaining difficult and contemporary issues in very easy way. Soothing to watch him elaboration. He simply was able to easily grasp underlying principles and master new information that I do not need to be as diligent as others to achieve a good result.

Superb Sir
