Хочу стать медсестрой, но боюсь учебы с тремя детьми! Какие есть программы для подготовки к RN и кодингу?

I honestly just want to go to college to be a RN but deathly afraid that I won’t be able to make it, especially with having 3 under 3. I wish I knew of someway that I can take like a practice course to see when and where and for how long I can actually study for. Motivation ain’t the problem it’s the sleep deprivation.
OR I was also interested in medical billing and coding.
Can anyone tell me of programs ?
