Luke seems like a genuinely nice guy, and is available for help, but taking his class will decimate any chance you had at learning mechanics. Homework and discussion problems are simple, exam problems are impossible. He doesn't seem to care about the discrepancy, or teaching in general. Avoid at all costs!
