Im not too familiar with how officer and especially pilot selection is processed. But from what i do know.
You dont need a high GPA to be a pilot, really dont need anything above a 3.0 however, i would suggest having atleast a 3.3 or above since the selection at times could be very difficult and selective, the number of officers we accept always vary. The selection board is twice a yr for pilot and nonpilot jobs, with being an officer you will be limited to the jobs you qualify for and if you wanna go the special ops route whether combat control or pararescue, you cant go that route during the initial process, you have to be in the air force already to go that route.
Having your aviation license will definitely help a lot during the selection process, volunteer work, school clubs, community and a good GPA with 3-5 reference letters.
The AFOQT is the hardest test you will ever take and you can only take it twice in your life. The army only needs a passing asvab score to be an officer
