Hi nahidbari,

It sounds as though you'd go to the "best" school that will give you a full-scholarship (or an equivalent situation in which you could take out a full loan for the cost of the education), which is fine.

Part of convincing a Business School to "choose" you among the many applicants is two-fold:

1) Have a strong overall application with as many great aspects (GMAT score, essays, work experience, etc.) as possible
2) Convince the school how important its MBA degree will be to your career path and your extreme desire to attend school there.

If you can't satisfy those 2 conditions, then the school is not likely to pick you. Your questions are ultimately Admissions-related, so you should talk to an Admissions Expert (you can post in that sub-Forum on this website). My concern about your plan is not that a "lower" Business School would be skeptical about your application (with a 750 GMAT Score); my concern is that because you'd rather go to a higher-ranked school, you won't come across as being genuinely interested and excited to attend school at a "lower" program, so the Admissions Officers for that school would be less likely to choose you (your lack of excitement would come through during the application process).

GMAT assassins aren't born, they're made,
