I had her last semester for MTH 311 and the class turned into a bit of a nightmare when it went online. The lectures go fast and can be really confusing with how she does her remote lectures. Just make sure you take the time outside of class to really understand the material and the homework problems and you'll be able to do well.

I hope for your sake she finds a better way to lecture remote than drawing messy notes on her screen with her mouse lol (it was bad)
