As a chemist I can tell you that there are many options for chemistry at the university level. Some are geared for health sciences (general overviews) and others are for science majors. What exactly were you thinking of taking? If it is general chemistry the course covers all that you need to know but you may wish to brush up on basic algebra skills. Or, you may want to review your calculus if that sequence demands it (mine did, it will help you derive equations).
If you were going to take the organic sequence the general chemistry is a pre-requesite anyway.
Let me know if you need any other help.
