Hi,
I am planning to apply for MBA this fall 2011.
Quick Background about me:

1: College GPA: 3.0 from UCLA... (um, but there were personal family reason I will explain)
Q1: should I go take additional courses at UCLA extension to boost my GPA?
Q2: Would the fact I past the CPA (certified public accountant) test with only one try in 6 months while working fulltime helping much with my poor college GPA situation?

2: Work Experience: 4 years /5 counting internship but with little to none outstanding accomplishments

Since I don't have a great profile on GPA or Work, I am planning to focus on GMAT and Outside work services;

Choice A: go on a mission for 6 months; I will be visiting and meeting with different Chinese business people while teaching English in China. (I am a Chinese)

Choice B: Initiate a community service project that will benefit my local community
(I have been very involved with my undergrad community service committee and served as fundraising director on the committee. As for now, I also volunteer at a tutoring project associated with LAJCC (Los Angeles Junior Counsel Committee). However, I haven't hold any leadership position since college

Q3: Which choice would help me more with MBA admission ? (For choice A, I will have to quite my work)

Lastly, due to my poor GPA, how much works (how outstanding I need to be in other area) to still have a chance with top tier MBA schools?

Thank you so much for your help!
