It's whatever you want to do.
There is no RIGHT decision.
FED IS BEST.
You could breast feed when you're home, pump and bottle feed breast milk, and supplement formula if you need to.
I had my daughter and not long after started my classes. I found formula was the best fit for us, and WIC helped me get it for free.
Whatever is less stress for you is best. Because if your set on breastfeeding but its too stressful then you not make a bunch of milk.
You'll figure it out, you could always try breastfeeding in the hospital and if when you get home you realize it's not for you then switch. They say the first 2 weeks worth of breastmilk is the best anyways so if you like it stick to it or if it's easier with your schedule then bottle feed. I bottle fed my first from birth, but I'm still deciding with my second which I would prefer.
If you're going to be working and going to school I'd say bottle feed .
I will suggest you to breastfeed while you will be at home and while going out for work you can use the breast pump to collect milk and store it in a bottle so that it will be feed later.
