ya know, this is what I don't agree with this...
Learning is the responsibility of the student, it has nothing to do with what the professor provides...
the professor has 1 primary objective and that is to "lead" you to learning a subject, yes I do agree that some prfessors are "good" (students can underestand thier english) and some professors are "bad" (you just don't know what theyr saying, why theyr saying it, just makes you wanna sleep)..... but the learning process is the students responsibility.
If you took an "easy" organic professor, good for you, thats a "easy" 4.0 which, I dunno about you guys, but I would MUCH rather take a 4.0 in orgo than a 3.0 with a "hard" professors..... I'll take the MCAT some time later and self-learn the stuff my "easy" professor missed....
The way I think of this is (and some will not agree with me), high GPAs (if it was an art major or a nuclear engineering major) will give you an easier time getting into med school..... not "halfway decent GPAs with hard professors"
The GPA vs MCAT are 2 COMPLETELY different battles, don't fight them both at the same time, meaning, don't go around looking for a "hard" professor so he/she can prepare you for the MCAT with the end result of you not getting that precious 4.0 or 3.5
One final think, I've had over 150+ credits of college work (undergrad + postbacc), I have NEVER had an "easy" professor that was actually crappy..... Meaning, the professor teaches you everthing you need to know in regards to the course (physics, math, chemistry, blah blah blah), but the MAIN difference I notice between a hard vs. easy professors are the exams..... the easy professors make exams "easy" and the hard professors make exams hard as hell, to the point where the highest grade out of 30 students is like a 55 or 60%, yes that was my physcis professor, the guy was a feaking genious (got his PhD in physics at the age of 20 or 21, he was nuts, and so were his exams).....but at the end of the course, I managed a B (which I know was curved, cause there is no way my 30s and 40s% got me to an average of 85%)
