I had to drop out the first time, partly due to child care issues, my course is not your normal 9-4pm mon-fri.
This time around, its the same course, but one extra child lol, but if I get in next year my older two will be 17 and 13 and my youngest 5, so he will be at school and they are both old enough to help with child care and weekends/evenings if my husband is working.
Child care is one of the biggest reasons students who are parents drop out apparently.
