Maybe they can take the one (ochem) for AP students. That Rizzo guy is teaching it an he is not that challenging, especially the first semester (his stuff is all over the web). There is more memorization than anything else, but based on the materials I’ve seen from his class, it could be far worse (it is a very standard level ochem course based on what I have seen). In fact, it appears the sophomore sections have a tougher line-up of instructors. The OP can have the benefit of being challenge enough while also not being thrown into an instructor’s course who is regarded as more difficult than others even among the experienced (sophomores). I honestly think the math classes there are harder so would worry more about that if I was taking someone at the level of Rizzo.
@CGI6737 compare this to what you did in highschool and gauge whether or not you can handle the jump for yourself:
http://as.vanderbilt.edu/chemistry/Rizzo/chem220a/Chem220A.html . That is honestly the best way of doing it. However, keep in mind, that you need to consider the context of your life at college in general and the fact that will no doubt be absorbed by many social events and EC’s. The raw content is still a good place to start. The site is a bit old, but this person hasn’t changed the way and level at which he teaches over the years (I decided to check just in case), so its a pretty safe approximation assuming he doesn’t make it easier for freshmen.
