Read MoreYou have excellent teaching skill , sir. You clarify the concepts through real geological example which enhance the understanding in a most efficient way. Structural geology was the toughest subject i used to find , now it seems to be understandable because of you. Thanks a lot for giving your time and effort . Hoping for more courses in upcoming days .

Read MoreFor someone like myself, who is not so good in structural geology, this course is very effective & fruitful !!! I think it is the best possible way to learn structural geology from scratch. Sir has put a lot of effort and ensured that various option are available to suit different learning style. He has shared every bit of his knowledge selflessly. He also showed examples from Google earth pro, which helped me visualize the problem. The live lecture session are extremely helpful and interactive. He makes sure every topic is covered and asks us qs afterwards. He also is very responsive to every qs & clears out every little doubt of us. He pays attention to each and every one of us. Thank you
