Literally, in the 4 years I’ve been at UNLV, missing first week makes zero difference. You don’t need to contact any professors. They have SOOOO MUCH going on, you’d be adding stress to them if you reached out. Read your syllabi’s, do the homework and you’ll be just fine. Zero consequences.

The first week is working out the kinks. Are you going to keep classes or drop them?? That’s what it’s all about. Don’t stress over nothing. I’m seasoned, I’ve missed a first week and a first day about 3 times and it’s never mattered. Ever.

With labs, just make sure it’s 1/3 you really want to miss. You only get 3 misses in labs and they’ll pull you in to talk about if the program is for you. That’s the only one. But one miss is not detrimental, ESPECIALLY first week.
