Hello,

National Testing Agency has released video lectures by professors from various IITs to boost the preparation of students who are not willing to join private coaching or do not have the access to them.

The link from NTA site redirects you to the videos:

Alternatively, check this link of NPTEL for GATE videos:

https://nptel.ac.in/course.html

Many other videos are also available across various platforms(like Youtube) free of cost.

Hope this helps.

Thanks.
