Depends on the courses and how they're taught.
For ours at my school A&P looked like this:
A&Pi (quarter 1)= Anatomy
A&Pii (quarter 2)= Physiology
Day 1: Memorize 100 bone features of the Skull (zygomatic arch, sutures, etc.) and read 40 pages
Day 2: Quiz on day 1. Memorize 40 origin and insertion points of nerves and the names of the nerves from the sternum/clavical/skull. Read 38 pages. ((Of course, one needed to know all the bones and bone features in order to accurately describe the origin and insertion points.)) Luckily, this was the "weekend".
Day 3: Quiz on day 2. Memorize all the rest of the bones and and 50 bone features of the upper body.
Day 4: Quize on day 3. Memorize all the bones of the spine, parts of the spine, all the nerves and origin/insertion points of the spine.
Quizzes were usually 6 questions (aaargh, 250:6 is a rough ration, no wiggle room!), biweekly chapter tests 25, midterms were 500, finals were cumulative (I think 800 questions? Including an oral section, microscope section, Franklin -our classroom skeleton- section, etc.). The tests were split between scantron, short answer, and diagrams that one had to fill in (or in physiology, create; like 'draw the krebs cycle, or illustrate the ATP switch.) My professor actually FORGOT to teach us neurotransmitters (headsmack!) so we all got 15 minutes before the final to memorize neurotransmitters. Fortunately we'd already done receptor types, agonists, etc... so we weren't too screwed, but that was one unhappy 15minute cram session! Murphey's Law... of course I was taking neurochem NEXT quarter. Sigh. If I'd taken it the previous quarter (a whole quarter on nothing but neurotransmitters, practically) I'd have been golden. As it was, there was quite a bit of guesswork on that section of the final.
The class only picked up in intensity from there. In general, I had to memorize 200-250 things for each class after the "lazy" first two weeks. Of course, none of us realized they were "easing us into" A&P those first few weeks! Oy.
In our area many the nursing prereq classes (not prereq for the prereq like bio101, but Pre-Nursing...A&P, microbio, 3 quarters of chem & 3 quarters of o-chem) are washout classes. Nutrition, Psych, Developmental Psych, Stats, Intro to Research.. those are relatively easy classes. But the hard sciences they WORK you. In our area the top nursing schools have about 6,000 applicants for 40 spots, and even the straight RN programs (instead of BSRN) have several hundred applicants for 40 spots. The competition is brutal, the classes are very very intense. The classes are also the same whether you're going for your RN or BSRN. Same classes, professors. No distinction. 260 & 261 no matter if your path was RN, BSRN, Pre-Med.
Most people I know either ONLY take A&P for those 2 quarters, or they pair them with a "fluff" class that requires zero effort. I've only ever met 1 person who took a full load with A&P. Most people manage full loads with Chem & Micro, but pare down for O-chem.
There is no WAY anyone is accepted to nursing school before all their genEd and prenursing classes are completed in our area, so count your lucky stars!!! (aka there's a lag year between prereqs and starting school... and in order to be a competitive candidate one needs to have that gap year filled before application with acceptance into some program of study or work that is healthcare related. Doesn't really matter what, medadmin, more volunteer hours; one needs several thousand volunteer hours to be competetive so people start those volunteer hours when they start classes an keep them going right up until they're accepted into school -and beyond, emt, phlebotomy, lab tech, whatver... but that year needs to be mapped out).
The coursework is INTENSE. (Have I said that enough, yet?)
That said... I only had childcare for when I was actually IN class. I did all my studying during naps, after bedtime, and later, when he was in preschool. Everything was literally "night before" (because that's all the time you have), but you DO have to retain it. There's no way to cram 500 q's out of a possible 3000 or so the night before. I had a 3.86 by the time I was done with my prereqs. I could have done better if I'd had more time to study, but all A's and A-s (and 1 B+) isn't awful. Thank god for fluff classes. I have 1 C on my transcript. That was the quarter I tried to bump up to 3 classes at a time, and learned how silly that thought was for me!!! Some parents can, I couldn't.
I LOVED when I had one weekend afternoon a week w/ childcare. Loooooved it. Only had that for a little while, but it really took the stress level down :) :) :) Also was a dedicated time I could get a study group together.
