I'm not sure if this has been tried before, but how about a time consuming (multiple choice) test for deterring crimes where an offender, in order to cut prison time, has to study hard and be mentally in involved with like 1000 questions for a few hours. Fail the test? You're given a week to study and take the test again. The type of test that is so annoying that once you pass you don't want to take it again.
