The OAT at a Glance

The Survey of Natural Sciences

In this section of the OAT, you'll have 90 minutes to answer 40 questions on Biology, 30 questions on General Chemistry, and 30 questions on Organic Chemistry for a total of 100 stand-alone, multiple-choice questions.

Essentially you have a little under a minute per question (52 sections to be exact). The key to remember is that some questions require more time whereas others don't take as much time. Begin with your strengths and answer all the questions that you are comfortable with. Mark the tough ones and come back to them at the end.
