Anyone who has ever taught developmental mathematics knows there is a problem in course placement. Some students test well and place clearly above their level, while other students place below their real capability because they either have been away from math for a number of years, or did not prepare for the assessment test. In either case, they end up wasting their time and money. Montgomery College offers two review courses that cover the developmental math sequence of Prealgebra, Elementary Algebra, and Intermediate Algebra. These review courses have proven to do a more accurate job of placement. In addition to helping the placement effort, we have found that the retention rate has dramatically improved.
