This is a place where free software and OER (openly-licensed educational resources) could really make a difference.

In my experience the online assessment solutions offered by most commercial publishers are horrible, while open source solutions like WeBWorK http://webwork.maa.org/wiki/Get_WeBWorK and MyOpenMath https://www.myopenmath.com/index.php are not bad and have been around for many years.

Yes they are not as "shiny" as the commercial offerings, but I'd trust them much more for actual learning/practice/quizzing than the mainstream publisher crap.
