<p>Chem 11 is still an intro level course - [New</a> Introductory Chemistry Courses](<a href=“http://chem.tufts.edu/newcourses.html]New”>http://chem.tufts.edu/newcourses.html) - it’s just a little more comprehensive than Chem 1. The topics are the same, the difference lies in its intensity. Chem 11 has more course time and tends to be a more difficult course, but if you’re planning on taking a chemistry/science related major, I strongly encourage you to look into taking Chem 11 regardless of your AP background - 11 is the course that will best prepare you for the major. </p>
<p>If you aren’t planning on a science related major, then I’m not sure why you’d be so keen on taking bio and chem at the same time.</p>
