I am a physics bsc 2nd year in a decent(not top) Indian Uni.I now have realised that I like math more than physics and want to do a masters in math abroad. I cannot switch majors and I can only take introductory group theory and real anaysis from the math dept.(Also intro probability,diff.eq,multivar calc etc mandatory for physics.Also 2 'math methods for physics' courses.) **There is this ONLINE portal called NPTEL which offers courses with assignments, proctored exams and a certification with percentage score.**The courses are offered by top public Universities in India. Will obtaining these online certificates with good score (in the needed pure math courses) help me attain admission in a good math masters program abroad?

I don't want to waste time and money for this if it is useless.

If not, what must I do? Is there no way?
