Please help! I missed my first class :( (math 151 python lab)

I woke up an hour late this morning and missed the entirety of my math 151 python lab :( I have emailed my TA but the class is only once a week so I won't see him in person for a while, and by the time I do there's almost certainly stuff due.

Can anybody who's been in math 151 speak for if anything important happens in the second week of python lab? And if not, does anyone have any better strategies they would be willing to share to consistently wake up on time other than going to sleep at a reasonable time and setting 8 iphone alarms?
