Hey I am taking Chem 222 in the Fall Semester at Concordia and the last time I took Chem 221 (Organic Chem) was a year ago in cegep. What are some things I should review during the summer ? Any specific topics I should really nail or prep work to do in advance?? I’ve heard it’s a really hard class and just wanna be the most prepared.
