  At the workshop on Trends in Functional Programming in Education (TFPIE) in
2015 Ionescu and Jansson presented the approach underlying the "Domain Specific
Languages of Mathematics" (DSLsofMath) course even before the first course
instance. We were then encouraged to come back to present our experience and
the student results. Now, three years later, we have seen three groups of
learners attend the course, and the first two groups have also continued on to
take challenging courses in the subsequent year. In this paper we present three
examples from the course material to set the scene, and we present an
evaluation of the student results showing improvements in the pass rates and
grades in later courses.
