The optimal amount of time spent studying is where the marginal benefit (the additional benefit gained from one more minute of studying) equals the marginal cost (the additional cost in terms of time, effort, etc. of studying for one more minute). This is because at this point, the student is maximizing their benefit from studying without incurring additional costs that outweigh the benefits. Therefore, the best choice is to allocate time such that the marginal benefit of studying equals the marginal cost of studying.
