Consider a student studying for a biology exam

Consider a student studying for a biology exam. Would you expect study time to be subject to diminishing​ returns? Suppose productivity is measured as the anticipated increase in the exam score. Construct a numerical example in which the first hour is twice as productive as the second​ hour, which is twice as productive as the third​ hour, and so on up to five hours of study.
