Hey debayan,
Good to see you around

. Actually there is no "Separate" strategy to get a scholarship. The more the schools wants you to come, the more money they will offer you. It's more a less a strategic decision of enticement, although they may also take into consideration their perception of your need based on salary and family information as well as your essays, but mainly these scholarships are offered on a merit basis, so it will be on the strength of your application overall (and here there is no separate strategy beyond giving in the the best application you can).
Thank you Jon...

Yup! you're right again...not many schools offer need-based scholarships,it's mostly merit-based scholarships and for the latter it's really a strategic decision and as you've said- heavily depends on one's candidacy overall.So for this merit-based scholarships, most of the schools I guess,don't have any separate applications.In that case, applicants need to show their best strength through their essays only I guess.Is there any other way to showcase this...?
My second question is-In general how the need based offers are determined..? Is it based on the personal assets of the candidate solely or that of his/her family or else?
Look forward to your reply Sir..!
