@ChangeTheGame: “My daughter is taking Physical Chemistry as a Senior and taking her Analytical Chem and Instrumentation class out of a normal sequence (both by 1st semester junior) but before her pre-reqs for each to overcome her sequencing issue and go abroad 2nd semester junior year.”
How is she doing this? Was there consideration of AP work and/or other exposure to the material covered in the pre-req courses in which she did well enough to work in her favor (even if they did not afford her a waiver from college classwork) as far as assessing her ability/capacity to successfully do the upper-level work?
