1. The ASTB is the exam the services give to see if you have basic aptitudes for flt. You become a Marine officer after you complete Officer Candidates School and receive your commission. If you go to OCS during the summers in college, you'll have to wait until you graduate from school. Then it's TBS, API, etc, etc.
2. I believe the USMC recruiting website is www.marines.com. If that's bum scoop, try www.usmc.mil, then take the links to recruiting. Be sure to get an Officer Selection Officer, or "OSO," and not just a Marine recruiter.
3. Since the only "fighter" plane in the Corps is the F/A-18, your chances of getting "fighters" are pretty slim. Don't try to say the Harrier is a fighter. It's *A*V-8B. No offense. Point being, if you actually are born to be an AVIATOR, you'll fly whatever takes you from "the surly bonds of earth." Those who are wedded to a particular platform are usually more interested in it because it sounds or looks cooler. To put things in perspective, the USMC is mostly helos. The Army is almost exclusively helos. The Navy is also over 1/2 helos, with a good chunk of the rest being maritime patrol. The USAF has very few helos, but what proportion of its aircraft are fighters? Not very much. I'm not saying this to piss on your parade. I'm all for people who want to fly, just not if their goals are just to be cool. Just think about all that, and if you're still ready to go, then call the OSO.
