@ucbalumnus Linear Algebra is a likely suspect, although I’ve heard tell that s311/312 covers much of its content more indepth than even the honors session. I might even get departmental permission for 403!
I also wouldn’t mind diffy Qs (they’re very applicable to my research!) but consensus among those I’ve asked is that the S343/344 sequence isn’t very good.
Either way, I’ve arranged to meet with my undergrad advisor tomorrow! I’ll make sure to ask her about 403 prerequisites and S343/344.
