Not too easy. Not too difficult.
This course work doesn't contain original course related documents taught at IIT-B. the documents simply contains NCERT Q&A of class XI and XII and a few of them contain formulas for IIT.
This course can teach you a lot if you are yet in high school but if you are in college then there is nothing to learn because you guys already have gone through all that.

Advice for students:
Only for the students who are preparing for IIT-JEE and not for the college students. It's kinda a trap. If I had to advice a school student about this course then I would just ssay that focus on what is being taught in school 'coz that is more than enough.
