How can I study for midterm exams?

yesterday, my book which I bought from book city received and I frankly tell you the book is like a gold and the style of writing is so easy and you didn't tired of reading. I love that and I have started to study from this book and the hardest pamphlet together . The final exam is becoming soon and I should be ready ! 

We have a midterm in this semester, after many months or even many years we have a midterm. I really forgot how can I study for the midterm. lol. One of them is general and the other one is specialized course. the next one is so important because this course and its teacher is new for us and relates to linguistics. However, both exams are in next weeks. I mean I have only two weeks to study.
