You're training your mind to think using organic chemistry principles and you can't do that by just looking at the answer. Thinking the problem through and proposing an incorrect answer is actually a characteristic of effective learning. Do not fall behind in your studying. New material in organic chemistry builds on the material preceding it. Allow yourself at least 15 hours per week to study, review and do problems.
Organic chemistry is very difficult.
The material can not be crammed. Study in groups. Research has shown that students learn more effectively in collaboration. This is the reason for the in-class group work you will be doing. Studying in groups outside of class or with your tutorial group is also beneficial.
