At the time of publication of the original research paper (1) there were three students who had pending grades that led to some misleading tabulations and slight errors in the reported data. However, the interpretations and inferences of the outcomes of the data were accurate. We regret these errors and submit the following corrections to the published manuscript.

The first sentence of the first paragraph of the section on Findings should read:

The D, F, or W rate in general chemistry for this university is approximately 47%. The D, F, or W rate for this class was 47.7%: 14.5% (n = 35) of the 241 students withdrew from the course, 19.5% received an F, and 13.7% received a D. Three students had pending grades at the time the data were analyzed.

The second sentence of the second paragraph of the Findings section should read:

Only one person (2.9%) of the total withdrawals had completed first-semester calculus and 34 (97.1%) of the withdrawals from the course either had no mathematics course on record or had not enrolled in calculus.

Corrected Tables 1 and 3 appear below.
