Imagine a student has a feasible frontier that illustrates the trade-off between their final exam score and their hours of leisure per day. Two specific combinations on this frontier are:

• Point A: An 85% score and 3 hours of leisure.
• Point B: A 75% score and 5 hours of leisure.

A classmate argues that Point A is objectively a better outcome than Point B simply because the exam score is higher. Evaluate this argument. Is it correct? Explain your reasoning and identify what crucial information is missing to determine the student's optimal choice.
