[edit] Test format

The test is thirty minutes long and consists of eighty free response problems. Problems can be solved using a calculator, and scratch work is permitted.

[edit] Problem formats

There are many types of questions on the calculator test.

  • "Punch-in" problems - single mathematical expressions which can be entered into a calculator directly to obtain an answer
  • Stated problems - various types of math word problems
  • Geometry problems - shapes with various dimensions and angles given and one which must be solved for
  • Significant figure problems - problems which must be solved using significant figures

[edit] Scoring

Each problem answered correctly gives you five points. Each problem answered incorrectly takes away four points,but some schools take away 9 points. Four or nine points are also deducted for using the incorrect significant figures in significant figure problems. Unanswered problems do not affect your score, but problems skipped before the last problem attempted are considered incorrect. Scores can range from -320 to 400. If you make a 400 it means you answered all the questions corect.

[edit] Calculators

According to UIL rules, any calculator can be used on the Calculator Applications test as long as it meets these requirements:

  • Commercially available
  • Handheld
  • Does not require an external power source (e.g., wall outlet)
  • Can operate silently
  • Is not user-modified

Any user memory should be cleared before the contest, but programs that came with the calculator can be used. A contestant may use up to two calculators during the contest.

Many contestants prefer to use RPN calculators during the test, which many say allow for faster input of expressions. A favorite is the HP-33S calculator.
