Klurfinator was my favorite teacher at BXV. His tests in APUSH were very difficult, but you basically knew what was coming beforehand (at least the essays were a breeze). He's also a really fun guy contrary to his reputation of being a stick in the mud. I've talked to him about GoT more than about classwork tbh. he also really knows his stuff and doesn't proselytize his political views (unlike dmax).
He knows the material very well and is helpful if you see him for extra help. He tells some interesting stories too. The econ class is hard tho.
Very interesting and fun classes. Funny and a great guy
