Updated for iOS 11

This app has two practice tests, each with two modules for a total of 132 multiple choice questions and their answers. 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
* 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

In terms of format this is not the best laid out app. However, it serves its purpose and is a good review. Some of the questions were actually used in the real keystone test. If the application had better formatting/options it would deserve a five star.
