Wake Up Call

I woke up this morning and suddenly realizing that I have 6 weeks left before the Final Exam starts. Oh my gosh, what should I do? 어떡애?

I don't understand a single thing that I learn in class. That's totally a lie, I do understand a bit but...

I guess this is a wake up call for me. No more playing around. I should focus solely on my revisions.

p.s: class starts again after a week of holidays.
