TYPICAL CLASS PERIOD: The first part, twenty to fifty minutes, of class is open for answering questions about the previous assignment including exercises, reading material, or classroom notes. You are encouraged to answer other students assignment exercise questions by presenting chalk board work. While presenting exercises is expected, this communication is not graded. Use this time to experiment with your ability to understand an exercise and convey your understanding to others. Don't worry about any mistakes you may make, that's part of learning.

The second part of class is used to introduce new material with examples and discussion. It is generally assumed that prior to the date listed on the Course Schedule, you took notes as you read from the new section(s). You may wish to include the textbook examples in your class discussion of new material and your instructor will cover these and other examples. Individual communication is not permitted in class when attention is directed to one individual. Some class time is devoted to group problem solving.

HOMEWORK: For each section listed below, read the topics discussed in class and work every other odd numbered exercise (1,5,9,...). Develop your problem solving methods on the first few exercises of a given type then work for speed and accuracy. Complete other odd numbered exercises if needed for mastery. Ask about the stubborn unfinished exercises at the start of the next class meeting! Develop a dogged attitude about doing homework problems on time and frequently review. Each exercise section will take several hours or more. Spread weekly homework evenly over four to six days for best results.

Ask for help if you need to develop better test taking skills. The final exam will count as two units.
