Re: Do I need to do very single textbook question on the syllabus?

Re: Built-in webcams/Equipment request [ENDORSED]
I think that they strongly recommend that we have external webcams because of the way that the lockdown browser works, but it seems like you can still take the test without one, maybe just less conveniently.

Re: Final Jitters
I always just try not to wake up right before the test starts, but rather give myself enough time in the morning to have a routine to make food, brush my teeth, etc. I also find it helpful to do some last minute review or practice problems to get my brain warmed up. Hope this helps!

Re: Reading the textbook
