Will Your Math Courses Help Me With My Wastewater Exam?

Although I am very highly certified in potable water treatment (T4) and distribution (D5), I have never worked in wastewater, nor do I hold any certification in it.  I do know from talking with people in that field, that many people in wastewater have had very good success with my Water Math Courses, especially with learning the math basics, but having never worked in the field I can’t personally vouch for it.  I also know from seeing some wastewater practice questions that there are certain problems my they will not cover.
