One daughter was pre-vet, which has the same required classes as premed students. She had multiple friends who were premed, most of who she met in the premed / pre-vet classes. She did take multi-variate calculus in university, and then took physics with calculus. She had previously taken physics without calculus, and she very much preferred the physics with calculus class. Some physics will be required for a premed student.
I agree with this. The world did not just end. The worst outcome is that you do not attend Dartmouth or Harvard, but instead you attend a different very good university with a very strong premed program. You might even have to stay in-state and save a ton of money that can be applied to medical school. Then you retake multi-variate calculus and get a better grade, or you get a better grade next semester in high school and do not need to retake calculus. This really is not all that bad, and will not stop you from getting accepted to medical schools.
This is a very good point. A very good university is still going to happen. Next semester you will want to do better in calculus.
To be honest I am not sure whether any of my various doctors use calculus on the job. I sort of doubt it. Perhaps a radiation oncologist, or radiologist, or a robot assisted surgeon, might use software that was written by someone who needed to understand multi-variate calculus. I do suspect that some of them use their Spanish from time to time.
This is most likely nothing other than a wake up call. None of us are perfect. We all have something that we would have liked to do better. We learn and do better next time.
