Well I fooled me. I gave you that type exam so that you might have higher grades - the syntheses were short, the mechanism questions very simple, both too few. What to predict. Be prepared to think and reason and work out answers. There's no magic way to study.
Panic is a waste of energy and time.
Just calmly work and plow through it. Those who panic don't have the confidence that comes with knowledge. Be calm and read the comment I just received from a student in your class. And follow the lesson I've told you all semester - problems, problems , problems. I did very poorly on first two exams.
