HOW TO STUDY FOR TEST
1. Review all powerpoints

Write out outlines of each slide in notebook

Study all tables and graphs on slides, study corresponding tables and graphs in the
book

Study pictures and know what they are (ex: if you see a picture of red blood cells
and a purple worm-like protest among the cells, what is it a picture of?)
2. Use your book

The best way to use the book is to study the pictures. Study all tables, pictures, and
graphs that are on both power point and in the book.

Read the summary of key concepts, if you don’t understand something, review it

End of chapter questions
3. SI worksheets

Get them all from the si website, get the answers in session or ask me before or after
class
