Well, i was in Chem 1A03 CO2 with Landry as well and basically gave up my friday off to have someone else. My only other option was Goward since you have no way of getting into Locks core (extremely high demand). Some dont mind him but since his main job is a lab coordinator and ppl hate him solely through the few times they see him in labs....i switched. This is not to scare you since some find him great....some, not at all. /I would have ended at 1120 on fri had i not switched :(
Good luck, and i would contact the department concerning your elective just in case
