Thanks a lot !!!
I will definitely add some top 30-50 schools.
For calculus, I have completed a course on Coursera. For Statistics and econometrics, I have completed courses on YouTube.
Having said that, I too believe I should have some formal course work in stats and econ which I shall pursue in the coming year (Can't do it now at this time anyways).
You mentioned that I have some weaknesses in my profile. Would love to hear if you can specifically point out those so that I can work on those weaknesses.
If someone can give a comprehensive advice, I would really appreciate that.
