Feeling lazy

Much to my relief, exams is are over (if you're talking about only one exam, you could say: "...my exam is over). I've never been so tired after the exams (or if you're talking about only ONE exam you should say: "I've never been so tired after AN axam). One more year before I graduate, and this will be my last student summer holiday.
At present, I'm staying in my room, listening to Avicii's "summer anthem", "Wake me up" and having some mangosteens. This seems to be perfect for a lazy, stress-free day. I haven't got the faintest idea where I will go, or what I will do during this "last" summer.

Great job, Luong!! You are writing English wonderfully!! Keep up the good work!
