Some of the multiple choice questions emulate constructed-response type questions. The practice tests simulate the actual test environment and typical questions asked on the real test. These practice tests cover most of the possible questions likely to appear on the computer based test and will help you prepare by testing your knowledge. Simulating the actual test experience when using this app will help you overcome some of the pre-test jitters before taking the actual test. The practice test app includes: * 132 Multiple-choice questions in two tests, each with two modules * Answer key * Pop-up calculator * Navigator to select questions in any order and status of how many questions you've completed * Flag selection to allow you to come back to a question * Scoring screen with estimated Keystone Biology score * Optional 75 minute timer to help you complete the test on time * Share your test results on Facebook and Twitter This product is NOT affiliated with or endorsed by Data Recognition Corporation (DRC). ## Keystone Biology Practice Test Screenshots -
