Selective School Mathematical Reasoning Sample Test Questions

The Selective High School Placement Test was designed so that pupils may demonstrate their reading comprehension, mathematical reasoning, and critical thinking, among other skills. The purpose of the examinations is not to gauge academic performance, but rather to assess a person’s general intelligence.

This page will discuss the Mathematical Reasoning portion of the test. Permit your child to reply to the following sample Selective High School Placement Test questions. Students will feel more at ease with the testing procedure if they are aware of the kind of questions that may be asked. Notably, sample test scores cannot indicate a student’s Selective High School Placement Test performance. The selection committee will not examine practice examinations and samples.
