first year back

So my original plan was to go back to school when my oldest child was in Pre-k (most kids start around 3-4 years old), but then right before my baby goes off for his big first day, I was blessed with (wait for it..) another child! and so my plans of school had gotten kicked back a bit.

Now that both babies are in school though I finally got myself signed up for school and am starting on Monday, but its been a decade since I last attended school and I'm completly freaking out! I like to be overly prepared and my mom told me to wait until after my first class and see what the professor says but I feel like if I show up without all my materials I'll look stupid..Idk but I do know I'm probably blowing this up because this will be my first official time being away from my babies and my comfort zone...does anyone have any advice?
