I'm a freshman college student and Ive started the PLC -14 program following in the footsteps of my brother who is A Marine HUEY pilot currently deployed in Thailand. Ive been Studying for the ASTB and Ive recently took it a second time and it seems like i failed it in my mind. It felt as if all Ive been studying from the supplements i was given and the Arco book i was given was totally different the spatials I had down pact in the book felt unknown to me this time around. I studied nothing but math mechanics and spatial and it seems I hadn't had a clue , could someone give me pointers because this is my future career at hand.
