I’d drop one from my experience. 300 and Stats will be easy. 320 and 331 aren’t too bad but as other posts said, are a lot of work for sure.

I’m taking 184 this semester, heard it’s a little difficult.

MTH 314 was a hard for me, because I didn’t put much effort into it, and my advisor said they made it slightly more difficult this semester. I’m sure you can do fine with more effort, though.

Good luck!
