1. ACA Biochemistry Review
Used w/ Chemistry Kahoot

2. Objective: Have the most x’s by the end
Every Q you answer correctly, you can take 2 X’s away from a team or add 2 to your team.
Cannot exceed the 10X’s you start with or dip into negatives.
Every Q you get wrong, you lose an X. We continue until someone answers it correctly or we return to the first team.
