Hey Spikey!
Good question....and the answer is yes, your chances do increase with being a reapplicant. The fact you interviewed last year puts you in an excellent position for this year. Honestly, I am surprised you did not get in last year. From what I heard thru the grapevine, half of the class openings are for reapplicants.
Of course, the chances go down with race, gender, and where you are from in Georgia as they are trying to get more females, more minorities, and stress the importance of being from an underserved area.
I applied last year (obviously did not get in) and was told straight up that living in Cobb County does not help me at all.
Best of luck to you....I am definitely wishing I had some of your stats!
