If you really want to become an ATC'er your best bet is to go CTI and apply under that announcement. OTS announcements are becoming few and far between and a new one hasn't opened up in awhile.
Not sure if you have a degree already but if you do you can complete alot of the 2-yr programs in 1 year. The cut-off age is 31 and I believe once you get your TOL (Tentative Offer Letter) that freezes your age. However, Be prepared for a long wait. Alot of CTI grads are waiting 2+ years from graduation to getting a class date in OKC. There is always the exception though. Other factors are involved, your geographic preferences, AT-SAT score and networking will play a factor on how quick you get hired and where.

Good Luck
