"Ah, if only I had one more day to study..."
That is the sentence I’ve heard and said the most before taking an exam when I was in college!
The truth is, I was badly managing my time.
I got used to not finishing the study plan I set for myself, or even worse, I sometimes gave up on studying for several days, being too absorbed by a thousand distractions.
As a matter of fact, I found out I had always been cramming everything into the last day before the exam.
