Hi Allywn,
Yes, studying NPTEL online courses is beneficial. Even, NPTEL certificates have a separate importance in an Engineering student's journey.
NPTEL certificates have the quotations of many IIT's and have the signature of many respected HOD's or Dean of IITs. It means they are certifying that you have completed this course successfully.
NPTEL certificates also pay a vital role in placements as they are the most upper body in India from where you can get certified.
