Questions 10 to 25 have several different formats. Unless otherwise directed, select a single answer choice.
For Numeric Entry questions, follow the instructions below.
Numeric Entry Questions
To answer these questions, enter a number by filling in circles in a grid.
• Your answer may be an integer, a decimal, or a fraction, and it may be negative.
• Equivalent forms of the correct answer, such as 2.5 and 2.50, are all correct. Fractions do not need to be reduced to lowest terms, though you may need to reduce your fraction to fit in the grid.
• If a question asks for a fraction, the grid will have a built-in division slash (/). Otherwise, the grid will have a decimal point available.
• Start your answer in any column, space permitting. Fill in no more than one circle in any column of the grid. Columns not needed should be left blank.
• Write your answer in the boxes at the top of the grid and fill in the corresponding circles. You will receive credit only if the circles are filled in correctly, regardless of the number written in the boxes at the top.
