He was kind of strict on doing homework, but he actually explained all the new material very well. He would also explain it in a way that makes it clear for the student.
Very cool guy. Hard course, only take Physics II if you are smart and ready for a challenge. Ask questions and do the homework/study. He knows what he is talking about.
Physics II is probably the hardest high school course out there... and no, joiner didn't really make it easy. but he definitely knows what he's talking about and he'll always help you if you ask! more than that though, he's a really good person and most people don't see that because of his silly jokes (i find them funny because of how bad they are haha). i remember he helped a student fix a flat tire during his off period, he really taught character physics ( tennis)
