I did really bad in this midterm. I was not careful about the webwork question and in classes I seldom took notes in this first half of term. My tips is obvious that we are supposed to do all the webwork problems carefully and listen to big and lecture carefully. Be sure to take notes in class and review them later.
The last question of first problem is the most difficult question of the whole exam. The question is evaluate integration 1/t^2sqrt(t^2+1) from 1 to sqrt(3). The reason is that two substitution are needed for the question. And we have to be familiar with sec and tan which we did not always use it in high school.
In the last half of the term, I will try hard and get a good marks in the final.
