or skipped questions, similar to Number Sense, but scratch work, markovers/erasures, and the use of a calculator is allowed. Results At almost all TMSCA competitions, students are ranked against each other in their specific grade level. For example, all eighth graders compete against each other, all seventh graders compete against each other, and so on and so forth. This ensures parity of competition since students in higher grades generally tend to score higher than students in the lower grades. Particularly at the high school level, there is a stark contrast between freshmen with little real math and science experience and seniors, who presumably have taken or are taking advanced placement science courses and calculus.
