Do students who have studied in aimms have higher probability of going to Harvard?
Hello,
No, the students who have studied in aimms or any other "famous" college because which college you study in does not matter. The only thing that matters is your grades, extra-curriculars, SOPs, Letter of recommendations, essays(if required during admission), and other transcripts.
The admission authorities of Harvard or any college abroad do not look at the college you have passed out from, they only look at your application form, your achievements, why you want to study at XYZ college, and what makes you worthy enough to study there.
In conclusion, the college does not matter, so work on your profile, study hard and you should be fine.
All the best!
