I need a vacation...

Argh! Bloody (or: damn) teachers! They say that if I fail one exam, I will have to repeat the whole semester of this course. I (need) / (will have) to study all night!  Ha-ha! I need a vacation right now!

Reprove = this what they do when you have done something wrong and the speak earnestly to you about it

Career = this is your chosen occupation that you are working in

I need a vacation..

Argh! Bloody teachers (this is a very British saying), they say that if I fail another exam, I will have to repeat the entire course. I need to study all night haha (pretty much only use "haha" in an informal setting). I need a vacation right now!
