Ok, I'll plan to not volunteer next semester. However, I still want to keep up with research so I can continue in the summer rather than having nothing to do (classes are not an option). My bad grades are mostly due to not knowing how to study when I got to college, but last semester I really turned it around and have an idea on how to improve even more, so I feel like it would be a waste to throw out my other commitments when my time management got a lot better. It's just that for orgo I think I needed to be consistently studying, rather than just the week before. I poured in the most time for that class but was just average in the class (it's notoriously difficult here).
