Psychologist Dr. James Wong argues that cramming before exams is less effective than spaced practice, where study is distributed over time.

readingWhich learning study would best support Wong's spaced practice claim?
A
Students often cram
B
Students who studied 30 minutes daily for 6 days retained 50% more material after 30 days than those who studied 3 hours the night before, despite equal total study time
C
Memory is complex
D
Some students study more
Correct Answer: B
Choice B is the best answer. Same total time + different distribution + 50% better retention proves spacing effect.
💡 Strategy: Learning method claims need controlled comparisons with equal total effort.
