Which Chem class should I take if I'm not good at Chem?

I’m a first-year psych major and I need to take one of these classes:
Chemistry 2 or 14A or 17 or 20A
Which one would be the easiest? Does anyone have experience in any of them?

Rather than looking for a “mick” it might be better for your future to look at the causes of not being good at chem. It is not an immutable fact of your life, it is the result of something and is fixable if you want.

Is it an inability to focus on stuff you don’t find interesting? Perhaps poor study habits? I think many students have the latter, having never been taught in 12 years of schooling how to study although they are taught plenty of things they promptly forget and never use again.

let me suggest reading the book “Make it Stick” over xmas break. Based in part on research done right at UCLA, it talks about what is known about learning and has advice for college students on how to apply it. Even if you could care less about Chem the concepts in it will be valuable the rest of your time in college.

To put the ideas in practice get the “Chemistry Problem Solver” book that has thousands of worked problems. Then apply the techniques the “Make it Stick” book teaches such as distributed practice and self-testing and you will do fine in Chem.
