I think you're definitely a solid candidate for top schools. With your age, experience, GMAT/GPA school. you can even try wharton, H/S as reach schools. I don't think it's a big deal to go from audit to tax and I wouldn't even concider it a negative. I'm guessing you also went to an Ivy, Darthmouth?
Either way I think your profile will be solid in strong GPA/Strong GMAT, Young with experience, and you have some content to write you essays about.
GPA: 3.67 at a top 20 university (per USNews ranking). majored in Accounting and Economics
Work: 3 yrs at a CPA firm, 4 when I matriculate. 2 yrs in audit, and the remainder in tax. Does this switch look bad? Also, the CPA firm is NOT a big4. Its a top 10 (in terms of size) CPA firm, however. I have my license, and was promoted after 2 years from staff to senior.
GMAT: 770 (Q:50, V: 44, AWA: 5.5) Easily the strength of my application, but I have seen a LOT of hi GMATs get rejected from schools they applied to.
ECs - Ran Cross Country and Track all fours years in College. Business Fraternity (limited involvement). Currently am still involved with the team and am starting an annual fundraiser for the team. And I volunteer in local races about once a month (nothing leadership though). Started the marathon relay team at work for local city marathon.
Age when I apply: 25 (2010 application)
Age when I matriculate: 26 (2011 matriculation hopefully)
I am MALE. and I have half white, half Chinese. I do not refer to myself as Asian American though.
I am interested in FINANCE. Though my other interests are Real Estate (both my parents are involved in RE). And International Business (I've been all over the world and took 4 years of Chinese in HS and 2 years in College)
i would LIKE to get into one of the following schools: Columbia, NYU, Northwestern, Berkeley, or UCLA.
