<p>I can’t comment on the professors since I’ve never had any of them, but in general, you’re allowed to take Linear Algebra, Differential Equations or Calc III after you finish Calc II. As far as I know, the order is completely up to you and your schedule. That said, some of the courses require a bit of a material from the others, but I really can’t remember which ones do since it’s been 3 years since I took any of them. Someone who has taken the classes more recently can probably give you better advice.</p>
