Hey there, your IB scores and test scores are wonderful. You should be proud.
Its a little difficult for me to make sense of your grades. You mention a C, but yet your GPA is 3.87? And the highest GPA possible is 3.92? What is your class rank?
Ivies/stanford/etc will be looking for students in the top 1-2% of the class. For URMs they are often a bit more flexible. But as an Indian male, you’ll be expected to be near the top. If your rank is not that high, then seriously look at other schools.
Also consider applying ED to school where you have legacy advantage. Undergrad legacy is better than a masters/graduate degree. It sounds like your mom went to some good schools and that can certainly help.
Finally have you considered the UK? They are less focused on the ECs and instead the IB/AP/test scores. And only 3 years for a degree. You’d have a decent chance at the top schools in UK (Imperial, LSE, Oxford, Cambridge).
