Brady,
Save your money....study guides for the FAST test are cheap....get as good an education as you can heavy in Math, Physics, English, and Science.
Create relationships with people who will provide references for you that show you to be capable, reliable, resourceful, honest, and dedicated to becoming an Army Officer.
Take the FAST test and the other tests required for meeting the entrance requirements and do well on the tests. The next step would be a Flight Physical...make sure you pass that requirement.
You do not need to spend money on helicopter flying to qualify for the WOFT.
Also...consider getting a four year degree...do the ROTC program...then upon entering active duty request Flight School and assignment to the Aviation Branch.
