First I find the ESGs that are over the things that I plan to teach that week. I don't have to do this at school.
Most schools have keyboarding or similar classes which have computers with internet access.
Now you can give students an e-mail address that you want scores sent to, then give an assignment to be done during unstructured time in that class. Once they have mastered an ESG, they can do the version that sends the results to the e-mail address you give them. Or, they can send the results to their own work station and print the e-mail. I plan to have the test for that chapter. Those that need repeated exposure to catch on to a skill or set of vocabulary terms stay at it until they get it right.
