ok so I missed my lab because of a really stupid reason which I am not proud of. But I know that there is a make up lab week for the course at the end of the term. Do I need an MSAF form to reschedule my lab? Because...I kinda used it already :/

i dont remember if u sign up for a makeup lab or just show up to it. ask ur prof

Email the professor apologizing and explaining to him what happened. Some professors are really nice and understanding.

I had a friend who slept through a Physics 1E03 lab first year. He had Dr. Okon. My friend went to Okon and said he missed his lab. The prof asked why and my friend said "I'm just going to be completely honest, I slept in. I hit my snooze button by accident. Is their anyway I can make up this lab?" Okon laughed and let him make it up, no fuss about it. Definitely talk to your prof. Be honest and they might cut you a break.
