Ballasm

I am partly writing this because I need some SERIOUS reassurance that I CAN DO THIS. 😓😓😓 I have a 9 month old baby whom is primarily cared for by my father in law (whom lives with us) while I'm in school. Except that, in 2 weeks he's scheduled for surgery. My husband works 7 days a week with the hopes of getting off 1x week for his Pop's recovery. Smh. My school is 1x hr away from home, whereas my work (20hrs/wk+) is 2hrs south from my college's location. I do have lots of family to babysit should I need them. As for the class, I'm quite nervous. I've taken AP 1 & 2. 1 in summer with Chem and 2 in spring with 2 other classes, not bad, I passed. What should I expect?
