You should take the course.. end of conversation. It is very useful, and you don’t have to take the test, back at home, they even provide the bikes to ride during class so if you drop it.. no big deal..
Also.. if you ride. Get a a real jacket, one that won’t shred to pieces if you happen to bite it at 30mph. Ride with something other than low top tennis. Change shoes at work. Something to cover your ankles, boots are good, actual riding boots are best.
