Chemistry Test Taking Tips Name: ________________ Class#_____ Chemistry Test Taking Tips • Put a next to a question if you are unsure, and move on. Then go back to it later. • Try ALL 3 essay questions (#37-39). Your best 2 will be graded. The 3rd one will not count. • Describe ALL 3 variables when referencing the GAS LAWS (questions #33-36, 39) • Ask if you have a question. • Check your work when you’re finished. Are any left? You do not have to finish the test this period.
