Well guys; I certainly had quite the experience this morning.
I must be one of the luckiest people in the world when you come in about 40-45 minutes late for class (each class is 90 minutes) and your professor basically says its alright after class (and yes, walking in on class was somewhat awkward). Turns out, I ended up coming in when they were about to talk about the more important content of the day. Either way, the reason why that happened was because I ended up working very late on something for another class, which caused me to get barely any sleep; in the end, it ultimately had less content then originally planned. As a result, I got about 3 and a half hours sleep and I ended up falling back asleep after having my phone out on my bed, which leads me to where we are now. I REALLY need to make a habit of going to bed early on Tuesdays and Thursdays, as I can't really sleep in as much as I usually do.
Either way, a lesson learned; I plan on not letting it happen again (I had a more minor case where I was about 10 or so minutes late, but that was less significant).
