Labs are a very critical part of any biology course. Throughout your undergraduate major you will spend more time in labs than in lecture, and there is a good reason for this. In lecture you are usually a passive learner, while in lab you are an active learner. Too often I have seen these students miss a letter grade due to a lax attitude in lab. Take a Positive Approach Toward the Exams.
Exams are often the most perplexing part of a course to students.
It might be useful at this time to reflect on a professor's philosophy of exams. They are, after all, the major tool that we have to evaluate your performance in learning the material. Forget all of the arguments about how exams don't really test your knowledge because you're so traumatized by them that you couldn't write a coherent answer. They may be interesting arguments, but unfortunately they don't change the need for exams. Therefore, the exams that you will take will have representative questions from various parts of the course, but not necessarily from every facet of the course.
