Reminders
Chapter 3
- My e-mail address for school business is kzahm@mpsri.net. I check this frequently at school and less so at home. I can also be contacted at kevinzahm@gmail.com These should be constant for several years, so write themt down and let me know how you do in college (especially in Chemistry!). Also, you can easily get in touch with me for questions you don't want to ask during class.
- I won't always assign problems from the Student Study Guide & Workbook, but you may find it helpful to study from it anyway! [hint]
