I just registered last night for the '04 MCAT...
1. Go to
www.aamc.org
2. Next, click on "MCAT" (on left side of page)
3. Next, you will be taken to a new page. Here, click on "Registration"
4. A new page will pop up. Here, click on "Domestic."
Everything is smooth sailing from there!
The process is a little long (there's quite a few things to fill out). However, there's nothing difficult about it...
Before you start, however, you might want to get an idea about where exactly you will be taking the test. Kaplan has a test site rater. The ratings are based upon the reviews of students who took the MCAT in ''02 and '03. I found it to be quite helpful!
