hi ashley,
it depends on the school. the lvn school might take some of her general education classes like english and math. so she would be taking less classes. in my lpn school, we had to "challenge" their final exam for that particular general education class. if you pass, then we get the credit and do not have to take the class. if you fail, you have to take the class even if you have taken that class already in college.
the best for your friend to do is call the lvn school and ask them. hope that helps and happy new year as well.
