BU Transfer Chance

I’m currently a sophomore at SJSU (One of the California State) and thinking to transfer to BU as junior in fall 2020:
I previously got rejected by BU as freshman with 3.3-3.5 HS GPA (not great, but mainly because I moved from other country and I don’t speak English prior moving to US). Now that my GPA at SJSU is around 3.72-3.75. And I’m an officer position (and founding member, not sure if that matters…) for two clubs that I’m running and I’m wondering:

  1. what are my chances for getting into BU as transfer for CAS as sociology major? Or do I need to put CGS just to be safe? All I want is to get accepted!!!
  2. how many rec letter does BU want/ require for transfer ? Does it matter a lot?

Please let me know if any of you have any idea of what are chances for getting in, or anything else I should be aware while applying.

Thanks!!!
