I was originally planning to have a separate blog addressing this question as I took the course, but the answer doesn’t warrant that much writing.
The reason organic chemistry is so infamous is because it requires a lot of upfront learning of its basic language before you can begin to do anything useful. That, and the professors are typically knowingly awful.
My recommendation is to find a good textbook and do practice problems until you are comfortable with what is going on. A general hint: follow the electrons!
