studying

During mid-term exams, I was worrying about Linguistics and the History of the English Language so much that I did not pay that much attention to Understanding of the English Education because it seemed easier than the first two. I did so-so in the first two exams, but I had no idea that I would score that bad in Understanding of the English Education class.
I think I should study more from now.
I already payed for my TOEIC exam on May 31st but I did not study for that yet.
I must study more from now.
Today in Linguistics class, we learned about Phonology, but I could not understand a single word due to my lack of studying the night before.
I was planning on staying awake the whole night for the quiz in Linguistics today.
I stayed up until 3 a.m., but I did not study.
I was helping out someone I know who asked me to translate something,
but I had time to study but I did not.
I did not do well on the quiz.
