I unfortunately can't talk specifically to those A / C schools but I can talk in general about what I saw at my school and what I've heard about others.
It'll be a combination of theoretical classroom training and practical training, broken up into modules with progress tests. You'll have a GPA at the end of it, and traditionally, the higher you perform in your A/C Schools, the better your selection of orders when putting together a wish list at the end of the training.
You'll get evenings, most weekends, and federal holidays off.
As far as homework goes, there may be some coursework that is take home and written, other stuff you might have to stay late in the class/building to study.
When you get there, you might be in a holding division where you do things like quarterdeck watches (answering phones, doing fire and security roving watches, raising and lowering the flags for Colors, being a duty driver for folks who need a ride to/from medical, etc.), clean up / collect trash, do other janitorial/landscaping type jobs until your class starts. Once you're in class, you'll probably be assigned to a duty section that meets a certain number of times a week - at a minimum you'd probably muster with your duty section. On the weekends you'll have to do cleanup duty, and weekends/weekdays you may be expected to stand a quarterdeck watch when it is your duty section's duty day. They understand it's a school environment, you will have downtime even during the watches during which you can study and do classwork.
You'll live in the Barracks, more than likely with a roommate. You'll both be responsible for keeping the room clean - it will be inspected typically once a week, and you'll get a feedback sheet that shows you what you got docked points on. Repeated room failures can lead to administrative action, like restriction or extra military instruction (ie, cleaning facilities and whatnot or writing an essay on the importance of maintaining a sterile environment). ALSO while you live in the barracks, you'll probably have a work day (could be on the weekend, ours was on Sundays around 7 PM) where you get together and clean the shared spaces, such as hallways, lounge rooms and bathrooms.
You will probably have to muster in the mornings with your division before class, and march to class as a unit (as you would do in boot camp).
Besides all this... There's more than likely going to be a liberty phase system. Ours was broken up into 3 phases, and I wish I could remember the specifics of it... The first phase you weren't allowed off base during the week if I remember right, but on weekends you could leave, but had to wear your dress uniform, had a curfew and you had to have a battle buddy. Phase Two let you go out during the weekday... I think you could wear civilian clothes, but you still had to have a battle buddy and you still had a curfew. Phase Three let you do basically whatever IIRC. "Phasing Up" took about a couple weeks each step, and obviously getting in trouble (from academic perspective to failing room inspections to having contraband in your room) could result in you losing your phase privilege.
Also... because you're living in the barracks, you'll basically be getting just your base pay. You won't get a housing allowance and you won't get a meal (subsistence) allowance because your meals are provided for in the chow hall. If you're allowed to go out in town, you can of course buy whatever you want to eat.
If you do know a foreign language, it behooves you to take the time to take the DLPT, if you can schedule one while you are in A/C school. Depending on your scores, you can get an NEC (navy enlisted code) for the language that goes on your record, and depending on the language, you could be eligible for bonus pay for it.
