As flieger stated it is highly competitive, but if I get your post correct you are a jr. in hs. right now.
Now let's play the wheel of fortune.
Hurdle 1.
~~~ AFA or at least AFROTC. What is the rate @15% for all those that open up a PCQ file? 25% of those that enter do not graduate
Hurdle 2
~~~ Get UPT, best chances as an AFA cadet.
Hurdle 3
~~~ Graduate UPT. 25% will bust UPT. IFS is now waiverable, but before they did that, 25% busted IFS, never went to UPT. Typically only 25% will get fighters.
Hurdle 4
~~~ Become the shining star at your OP base and get Wing support.
Hurdle 5
~~~ Get selected for TPS
That is your next 10 yrs., at least regarding hurdles. As you can see when you start doing the math, the answer is exactly what fliegler stated.
HIGHLY selective
