This is an example: a research team from Harvard Medical School conducted a memory experiment for this purpose. The researchers divided 24 participants into two groups. On the first day of the experiment, one group kept enough sleep, and the other group stayed up until the next night. But both groups were allowed to sleep on the second and third nights. On the fourth day, the researchers tested two groups of experimenters and found that the memory of the first group was significantly better than that of the second group.

Will you take the exam the day after tomorrow? Then read more books today and tomorrow, and don't delay sleep.

Remember to get enough sleep the night before the exam!

Finally, I wish you success in the exam ~!
