Review for the test

You should use several tools to review for the test: 1) Go over your notes 2) Repeat step #1 3) Review chapters in the textbook 4) Take practice quizzes on-line (please don't send them to me unless I assign them!) 5) Use review and summaries at the end of each chapter 6) Make sure you know terms and concepts on the study guide: Study guide for test #1

 

Homework for week #5

Study for Exam #1:  Review chapter summaries, take practice quizzes, review your notes, read the book! You may want to do the practice quiz in Chapter 5 (Weathering), but I won't collect it or count the grade. You will need a scantron form for the test:  Scantron #4521 You can get this scantron form at the bookstore.  You will need at least 3 of these scantron forms this semester.
