I took the first orgo during the year, this course is doable, it just takes alot of personal effort i guess, make sure you practice alot of questions and go over all the tutorial problems.
you should be fine! but you could take it in the summer, it lets you focus on it more, without having to worry about other courses that you would have to do during the year. I like chem, so I didn't mind working at it, just practice lotss
i like orgo chem better than first year chem too, its more understanding!
