You don't "need" to go through Apple Training Courses to get AppleCare Certified. You can buy the AppleCare Certification Kit from the Apple Store $249 (US), study that and then sign up for the exams.
Apple goes through a company called Prometric (
www.prometric.com)to do their exams. There are tons of locations worldwide. A lot of them are at colleges. Yours maybe one of them. There are 3 exams, a Desktop, Portables, and Mac OS X exams. Each exam is $150 (US). In order to get certified you need to pass the Desktop and Mac OS X exams at minimum. This will allow you to work on Desktops and Mac OS X issues, but you won't be able to work on portables. If you pass all 3 exams you are fully certified to work on any kind of new(er) Mac. Those are Macs that aren't beige basically.
I just got done with a second interview for a MacGenius position at an Apple Retail Store near by and the guy I who was interviewing me said that they will train you if they want to hire you. Just because you're not certified, doesn't mean you won't get a position in an Apple Retail Store.
Also, you can go to
www.peachpit.com and buy 2 books. One is called Desktop and Portable Systems, and the other, Mac OS X Help Desk Essentials. These are Apple Certified Books that are specifically designed to train you for Apple Certification Exams. Both books are around $50 (US).
Apple Interviews aren't quite as bad as I thought they'd be. Basically you tell about your background, dealing with Macs, and other technologies. Then you go through about 30 minutes of Q&A where a recruiter will ask you a series of questions. Some are really easy, some are really hard. If you get a second interview, then you've done good. If not, then I wouldn't expect to get the position you applied for. The second interview, they didn't ask me any technical questions. It was just a meeting with someone from Apple and its basically a get to know you talk. You talk again about your background, what would you do in certain situations, etc... So you may know your Mac stuff, buy if you can't be a people person, Apple doesn't want you.
I hope this helps you.
