NEIU Placement Test Entering freshman students are given two options for placement into a math course:
ACT scores or the Math Placement Test (MPT). The university will use the higher of the two scores for placement into a math course Since there is no penalty to taking the MPT, freshmen are strongly encouraged to do
so, particularly if they took a math course in their senior year of high school. Freshmen with Math ACT scores of 21 or less are given the Basic MPT.
The Basic MPT is one hour consisting of a thirty minute test in Elementary Algebra and a thirty minute test in Intermediate Algebra.
Students with Math ACT scores of 22 or higher are given the Advanced MPT. The Advanced MPT is one hour consisting of a thirty minute test in Intermediate
Algebra and a thirty minute test in Pre-Calculus. Freshmen who do not submit ACT scores must take the Basic MPT. Please note: Calculators are not allowed to be used during MPT testing.

NIU The math placement test consists of 40 multiple-choice
questions: 5 choices per question, no penalty for guessing. You have 75 minutes to take the test, which seems to be
sufficient for almost everyone. The questions range from Basic Algebra through Advanced
Algebra (e.g. logarithms and graphing). There is a separate portion (20 questions) on trigonometry
which is required only if you are trying to test into Math 229 (Calculus 1).
You will not need a calculator and are not permitted to bring in any electronic tools, books, or notebooks.

Exponents are often used in volume problems to show the centimeters are cubed
Volume = (length)(width)(height) Length = 10 cmWidth = 10 cmHeight = 20 cm
Volume = (20cm)(10cm)(10cm) = 2,000 cm3
