TimeTest uses a random number generator to print arithmetic drills. You can choose from addition, subtraction, advanced subtraction (includes negative numbers), multiplication, or division. You can choose a maximum and a minimum range (from 0 to 999,999). TimeTest will print 50, 100, or 110 questions on a test. There is also an option to not allow duplicate problems. The test can be previewed and changed, if desired, before printing. An answer sheet can also be printed and will automatically adjust to any changes made to the test. The test can also be saved.
