Re: #51
The main problem with that is that AP and IB credit, where allowed for subject credit and advanced placement, can only be applied to entry-level courses. So the student may not be as far ahead in progress toward graduation in terms of subject credit and placement as s/he may be in credit units. If the student’s major has a long prerequisite sequence, then forcing him/her to graduate early due to the AP and IB credit may make scheduling more difficult than graduating on a normal schedule without any AP or IB credit.
