These questions are to be used as a basic review only. There are many good questions in the lab manual, both in the labs themselves and in the review sheets at the end of each lab. Please do not expect to see the exact same questions on the exam. Also, just because there is a question about something on here, that does not mean that it will definitely be covered on the exam. AND just because there is not a question about something on this review, this does not mean that there won’t be a question about it on the exam. Study, Study, Study, and don’t forget the images site.
