Ashanti finishes her multiple choice history test but there are still 20 minutes left of class. What should she do?

Turn in the test, and use the extra time to finish her math homework
Read back over the test and double check her answers
Count how many “A” answers she has and make sure it accounts for 25% of all test answers
Sit at her desk and wait until the end of the period to turn it in

The best option would be to read back over the test and double-check her answers. This will allow her to review her work and make any corrections if needed, ensuring that she didn't make any careless mistakes.
