Some schools are teaching the required math with the engineering principles and include all the prerequisite skills built into the sequence. There are a lot of students that struggle, some schools have found they are better able to serve a diverse set of students when they provide all the concepts a student needs within the curriculum rather than relying on all of the students to come with math skills they may not have been exposed to or mastered.
“Results of a recent longitudinal study have shown that the introduction of EGR 101 and associated prerequisite changes have substantially mitigated the effect of incoming math preparation on student success in engineering across the entire range of incoming ACT math scores, which has more than doubled the average graduation rate of enrolled students. Moreover, it has done so without watering down the caliber of graduates, who have actually enjoyed a slight (but statistically significant) increase in graduation GPA. Finally, the approach has been shown to have the greatest impact on members of underrepresented groups” - from Wright State’s white paper https://engineering-computer-science.wright.edu/sites/engineering-computer-science.wright.edu/files/page/attachments/WhitePapers_dean_v4.pdf
