OC Thinking Skills Sample Test Question

The Opportunity Class Placement Test was created so that students may exhibit, among other things, their reading comprehension, mathematical reasoning, and critical thinking. The objective of the exams is not to measure academic performance, but rather to evaluate an individual’s overall intelligence.

This article discusses the exam’s Thinking Skill portion. You may have your kid answer the example Opportunity Class Test questions provided below. If they are aware of the kind of questions that may be asked, students will feel more at ease with the testing procedure. Notably, though, sample test scores cannot be used to predict how a student will perform on the Opportunity Class Placement Test. Practice tests and sample exams will not be evaluated by the selection committee.
