<p>1) Whether he will need another semester of lab will depend on whether or not his college awards lab credit for his CC or AP class. (Some colleges do; some don’t. He’ll need to look at his transcript after he has started classes.) </p>
<p>If his college does not award lab credit for gen chem 1, then he’ll need another semester of lab. Biochem lab will probably be acceptable substitute. The best person to ask about this is the health professions advisor at his college. It’s their job to know this stuff.</p>
<p>2) AP Chem covers all of gen chem 1. Depending on the specific college’s curriculum, AP Chem may or may not cover some or all topics in gen chem 2. (IOW, colleges will award either 1 or 2 semesters of chem credit for AP Chem. It’s program-specific.)</p>
<p>If your son is concerned about knowledge decay for gen chem, he can spend some time doing a self-review this summer. There are some pretty good You Tube video lectures/lessons out on the web. He could also read his old chem text and do the practice problems at the end of the chapters. He could also look for and do any practice exams posted for gen chem 1 at his college’s or other colleges’ chem dept websites. He could also audit gen chem thru MIT’s online courseware.</p>
