# ACCUPLACER MATH REVIEW SHEETS

The Accuplacer exam is a branching exam. This means that when you miss a
problem, it will branch to a lower level

problem. When you get a problem right, the test then gives you a slightly more
difficult problem. In this fashion, this

test is very accurate in determining your placement into our DMAT/MATH program.

The first exam that you will be given will be the Elementary Algebra test.
Depending on your score, you will then take

either the Arithmetic (to place you into DMAT 0090, 0097, or 0098) or the
College- Level (to place you into DMAT

0099, or college level math classes).

If you have had two years or more of algebra in high school, it would be wise
to study all of the topics on this sheet.

However, if you did not have much algebra or feel very weak in algebra, you may
want to devote your time to studying

only the Arithmetic and Elementary Algebra Topics.
