Hi Diane! How old is your baby? I know too well what it is like studying with work and kids. I did the majority of my studying after the kids went to sleep, from 9pm to 2am or so every day. I also took off from work one week before the test. It is hard, but if you know the right approach, you don't have to go through a lot of materials.
Good luck to you!
Keep on asking, and it will be given you;
keep on seeking, and you will find;
keep on knocking, and it will be opened to you.
