My experience with university is that one can easily get at least a B+ if one attends every class, completes every assignment, and attends every tutorial to ensure they understand most, if not every, basic concept. So, I never understood why students could complain that a class is too hard, especially for classes as fundamental and structured as organic chemistry. I'm sorry to break to the snowflakes, but Organic Chemistry is easy. Can't we just tough up? Or as my professor used to tell me when I was trying to explain to him that I got B+ for my complex analysis course because that class "was too hard": math is math. Don't look for excuses.
