Difficult Subjects

A subject I'm finding quite difficult is Science, even though I have gotten quite a few good marks. Whats hard for me is that every once in a while, I get lost in the notes and the new ones come in a little fast. One thing I do like is the experiments we get to do. My favorite activity from this subject was the thinking the most questions as we can with my group, I thought I could have improved on the questions though. One thing I would love to learn in this subject is to be in depth with electricity, for example, hydro electric dams.
