Mei Mengzhen's predicament still concerned her studies.
She had drunk Spiritual Spring Water, which is known to enhance memory, so her memory was indeed excellent.
If she glanced at something briefly, she would remember it very clearly at the time, but a few days later she would forget. However, if she looked at it carefully, she would remember it for a very long time. Yet, although her memory had improved, her natural intelligence remained the same.
That is to say, she remembered all the content of the textbooks she had read, but her intelligence was such that comprehension was not guaranteed.
With the intelligence of a person in her thirties, she couldn't possibly apply knowledge from senior high studies in a flexible and practical manner. Therefore, with her current amount of knowledge, she still might not be able to gain admission to a top school.
