Things could have changed but I believe “placement testing” was referring specifically to math/english. Exemption was based on your SAT scores. You could google it and see what you find, I’m sorry but I don’t remember.
Per the “Gosh I should take the class” vs. transfer the AP credit - in my opinion - don’t waste the time.
Based on the following experience -
My foster son did take the college class (with chem) and was bored out of his mind. Yeah it was an easy A, but you are in college to learn stuff not get easy A’s! It would have been 4 credits better spent on something new (in retrospect). He got a 5 on the AP exam and tutors chem now, so your mileage may vary (YMMV).
My daughter brought in 28 or 29 AP credits and I have never once heard her lament that she missed out on something by doing so. She was homeschooled until high school, then attended a huge and well regarded NJ public high school.
(just giving context) She is a junior by credits and has a 3.9 GPA at Rowan (although it is only her 2nd year there).
If you earn 4s or 5s on AP exams Rowan accepted and granted course credit as appropriate. You do have to pay to send that info to Rowan, but it is not much and in our case will save us a year’s COA.
So two different topics covered above - standard placement testing which you can exempt by above average SAT scores and AP credit transfer which I advise you to run with
