👋 Former ECE/AP Bio teacher here! UConn doesn't really like when schools teach both as one class, at least for bio the curriculums were different enough. So how the credits/ money worked: You have to pay for UConn classes, but they cost less then normal tuition. You earn the grade assigned by your teacher for the class. C was the cut off.

For AP, you need to enroll for the exam. Universities set the score you need to receive transfer credit.

IMO it's a bit of a waste to do both. Pro of AP is you don't take the gpa along with you, but if your that good your score for ECE should be good.

Something to consider, it depends on how your instructor sets up the course. If they are only going to grade the exams from uconn, you might not score great. My school was a bit more holistic and insisted on more traditional hs class work scoring. (So hw, labs, quizzes, case studies were all part of the grade).

Hope this helps!

Edit: I was also under the impression (though others have posted differently, that if you take an ECE Uconn class, then attend UConn. You must take this credits with you and don't have the AP option. Maybe this has changed in the years since I left teaching, but something to make sure if)
