Do not count on last minute cramming right before exams to do well.

不要考试前的最后时间里靠死记硬背去取的好成绩。

Cramming might work (i.e. get you decent grades in the exams) during the first two years when the material is relatively simple, but if you don't learn the basics well, you might end up having trouble with the more advanced material that will build on the basics.

在前两年题目比较简单的时候死记硬背也许有用（比如在考试中取得不错的成绩），但是如果你不打好基础，你可能会在遇到进阶题的时候觉得困难重重——因为这些题都是建立在基础知识上的。

It might be hard to catch up once you have a gap in your understanding in the early years.

一旦早期在理解方面落后，后期赶上去会非常困难。
