transferring to elite national research universities

Why did you apply to Brown?

Did you apply to some target/safety schools that meet your criteria? If so, what are your other options?

I don’t think the shotgun approach is going to work so well for trying to transfer to this schools. You’re going to need college professor recommendations - and the more specific and focused a case you can make for one particular school the better your chances. Better yet, have a professor(s) call and email their friends and colleagues at the other school on your behalf. I can’t see a professor putting in the effort needed for all your dream schools.

Best of luck
