What is the time limit for the Survey of the Natural Sciences section?

The time limit for the Survey of the Natural Sciences section of the OAT is indeed 90 minutes. This section is designed to assess the test taker's knowledge and understanding of natural science concepts, which include biology, chemistry, and physics. A 90-minute time frame allows sufficient opportunity for students to read through the questions carefully and think critically about their answers, ensuring they can demonstrate their competence in these subjects effectively. The structured timing also helps maintain a consistent testing environment for all candidates and allows for a balance between challenging assessment of knowledge and the time needed to think through each question properly.

In contrast, the other time limits provided in the options are either too short or excessively long for this section's purpose, illustrating that the 90-minute mark was likely chosen after careful consideration of the material covered and the skills required to succeed in the field of optometry.
