Problem-solving strategies which don't guarantee solutions, but make efficient use of time is Heuristics.
Any problem-solving strategy that employs a practical approach or numerous short cuts in order to provide answers that might not be ideal but are adequate given a constrained timeline or deadline is known as a heuristic, or heuristic technique.
Heuristic methods can be used to expedite the process of obtaining a workable solution in situations when it is impossible or impractical to discover an ideal one. Heuristics are mental efficiencies that reduce the cognitive strain of decision-making. Heuristics are tactics developed from prior experiences with challenges that are comparable.

This would be a very important step for him to understand how the practice in problem solving affects the ability related to it. Otherwise, he will have a distorted result.
