this place is stealing my soul man. it's a ton of work, but i love every minute of it. i think part of it is because i know for a fact that this is what i want to do. some of my buddies here aren't so happy, since they didn't technically get into it because of their desire, but more for the monetary reasons. to each his own though.
the thing about kaplan is that it's heavily dependent on the teacher that you have. i had an absolutely shitty teacher, who happened to be doing the M.D., Ph. D. program at Feinberg, so I knew he was smart, but hell, an awful teacher. i basically paid all that money and never really attended class. so i didn't find it all that worthwhile, but again, YMMV.
i agree with deepak. my regular gpa wasn't all that great, since i chose a major that i enjoyed, but wasn't good at (economics). i was going to switch majors during my junior year, but decided against it, since i was already chest-deep in the major and decided that the extra work wasn't worth it. my science gpa, however, was high, and was what was actually keeping my gpa where it was, since econ was dragging it down. i also did a lot of research, mostly in the field of nephrology, and got a ton of good recommendations from the doctors that i worked under.
gpa isn't everything for med school. to be honest, they make a bigger deal out of it than it really is. i know people who get into med school with 3.0 gpas, but they have other things to supplement it. the doctor that i worked under was a D.O., but world renowned for his research. he basically said that getting into med school is almost luck, because one thing doesn't really factor more than the other. it's everything put together that gets you in. gpa and mcat score isn't everything.
