:Description
Mathcounts competitions in all levels (School, Chapter, State, and National) have two rounds (Target and Team round) in which a calculator is allowed.
Students who are skillful in using calculators and have some training experience will have a significant advantage over students completely untrained. Calculator skills can help students solve hard problems and save time for other problems. The advantage is also evident for the SAT II Math test or AP calculus test.
