Teaching a class?
If you teach a Security+ or ISC2 CC course, I can give you a class code. Your students open decipheru.com/practice/security-plus?cohort=YOURCODE and from then on their practice is grouped under your class: you see which domains the group is weak in and how many have set an exam date, in aggregate. Nobody sees one student's answers. It costs nothing, and the questions are the same ones everyone gets.
Leave your email and I will send a code, or write to contact@decipheru.com.
