Could you help to correct my mistakes please (2nd part of the text)?

Hello everybody,

Here is the 2nd part of the text I translated. I'm asking for help. Could you please correct my grammar and stylistic mistakes? There are a lot of idioms in the text. I'm not sure about it also.

About exams (2nd part).
1. Here are a few tricks tо go through thick and thin of exams.
2. You should prepare for exams gradually, day by day.
3. Believe me, it’s better than a final assault (final push). I wanted to say that before exams, students try to learn everything in one night.
4. You should keep in mind that our brain absorbs small portions of data much more efficiently. 

Thank you.
