@mjrube94 My D was in that exact situation. She was straight A student in HS with little effort and has many AP credits. She still did struggle a little bit during the first semester in engineering school as she skipped all the 100 level classes in Calc, Chem, and Physics and basically taking most sophomore courses from the beginning. She did catch up in the second semester though and keep her freshmen GPA above 3.6. My suggestion to her was not to take too many credits in the first semester (only 14) as a transition considering the rigor of courses she took. Then she went up to 18 credits in the second semester. She will be a sophomore but with junior standing next semester and she will only need to take 15-16 credits each semester from now on.
