2014-2015 HONORS Chemistry Midterm Review
This review sheet is a list of topics and sample practice problems only. The practice problems
are good representation of what to expect on the midterm, but it is not enough to just study from
the review. You need to look over your notes, old review sheets, tests and quizzes, homework,
etc. Ask questions!!!! You may check your answers online and I am available Tuesday,
Wednesday, and Thursdays for extra help.
