any course past 5PM is labeled an LPS course.
CAS students can take LPS courses.
LPS Students can take core curriculum courses during the day as well - they just have to fill out a tuition reduction form. (These are non “LPS” courses because they are during the day).
HOWEVER, the only classes LPS Students can take during the day (with the LPS tuition) are the core curriculum and classes in your major. If the class is not in your major, for example a Wharton Class or a higher level economics class if youre a bio major, then you have to pay the full CAS tuition (which is a lot higher than LPS tuition rates).
