Finally, a quick MBA related advice: If you are about to join the MBA of your dreams after the summer, do exempt as many subjects as possible! I guarantee you that you will have plenty of “more interesting stuff to do” instead of revisiting “once more statistics”.

Probably, the tradeoff between some extra peace of mind now vs redoing IT&Business on October seems unclear now. But, please trust me on that one young future student, it will be a pain to sit trough classes you already have some serious knowledge about. Exempting now (exam, project, etc…) will not “totally spoil” your holidays, plus it can feel so good when you leave the room because you are not required to do course X, Y, Z and you can dedicate to explore some other interests.
