I think this chart is extremely helpful to a lot of students. It lets students know which finals they need to direct the majority of their studies to in order to get the grades they want. I've used this since freshman year, and it's really helped me a lot. I think students would be a lot more worked up and anxious about finals if they didn't have some idea about what they needed to get in order to maintain their grades. This chart is saves students from becoming overly stressed and worked up about finals.
