This is my philosophy !
If you want to pass an exam, you must have goals. My goal is to have an average note and to be graduated from my business school in Bordeaux (BEM).
So you have to learn intelligently !!! and not doing revision because of doing revision, you know what I mean ?
For the Human Ressource Management exam, I am going to learn the most essential content and to read (for my culture) the rest. I think I will be enough … and we will see.
