If a student evaluates that each additional study session increases their exam score by 5 points while costing 2 hours of time, what should they consider before deciding to study more?

When a student thinks about studying more, they should consider the idea of marginal analysis, which helps them weigh the benefits and costs of their decision. In this case, each extra study session boosts their exam score by 5 points, but it also takes away 2 hours of their time. They need to ask themselves if those 5 extra points are worth the 2 hours they could spend doing something else, like relaxing or working on another subject. For example, if they only need a few more points to pass, studying might be a good choice, but if they are already doing well, those 2 hours might be better spent elsewhere. Balancing time and score can help them make a smart decision about studying more.
