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
