I totally agree with the guy above (too lazy to quote, haha). I took genchem in high school (transferred the AP credits to college), physics 1&2 sophomore year of college. I was terrified of ochem because its a whole new ball of wax (since you cant really build on knowledge from genchem from this, although there is some integration, its really a whole new set of rules) and what people have said about how horrible it is, etc. etc. i had planned on keeping a clean "A" record in all my other prereq's for premed just to allow room for that "C" in orgo, if it happened. What actually ended up happening, was that the terror of the orgo subject made me study my ass off and I pulled A's in both orgo 1&2. This is by no means an effort to toot my own horn, I'm just saying that it definitely can be done. I had no background knowledge of this at all (as with most people who go into orgo 1), and just went in knowing I would have to work hard. Annddd by the end, I realized that the class was definitely not as hard as physics (in my opinion), especially physics 2, haha. that class just blows.
