I like to think of tutoring sessions as learning learning. It's never too late to start good habits, and it's amazing how simple and rewarding it is to approach one's studies in the right way. For my part, I like to keep things light but productive; I find that students learn the best when they're having fun and when their studies highlight the aspects of the work that they're interested in. Myriad studies have correlated interest and academic performance, but just anecdotally it's important to approach school in a way that builds a foundation, whether that's for further schooling or elsewhere in life.
