CHEM 293 - Problem Sets,...

As stated in the syllabus, there will not be formal problem sets or assignments. However, here are some problem sets from previous years; the "assigned" dates are approximate. You are strongly encouraged to work through the problems sets once the topic has been covered. Print them, and with your answers stick to the space supplied in each question. You have to pay attention to detail in your answers. Only check your answers against those posted once you are done, do not peek at the answers earlier, that defeats the purpose. Pay particular attention to whether your answers have the same type of detail as the answers provided! Additional statements for clarification are given on the answer sheets in green. Finally, it is possible that you arrive at a different answer for a certain question; that still might be correct (if there are multiple approaches, I have only listed a selection of acceptable answers). If you have questions, bring your answers (or attempts) to me in my office.

Each question in a problem set has a point value. "5 points" suggests that it should take you about 5 minutes to complete the question; should you need much longer, you are either too slow and need more practice, or you are going about it wrong. I suggest in that case you come and talk to me. You can expect similar style questions and point values for the exams.

Problems might be discussed in class, especially if I receive a request to do so.

...and Exams

The following are links to practice exams. The "Final" is much longer than the S17 Final will be, to give you more practice problems for Exam 2. The "Labexam" is a shortened version.
