Chemistry Midterm Exam Review 2013 These are topics from a traditional 1st quarter. If you used the thematic approach with me this year, you will notice that the topics are not in order of their presentation throughout the year. The final exam is cumulative so this review will help you with reviewing the concepts and calculations. Notice that I have connected chapters to each unit from your book.
