Why is your advisor recommending that you take two sciences with lab that first semester? “Because I’m a premed” doesn’t make sense - most premeds don’t do that. Considering that you feel that English classes will be easy for you, and considering that the English major overview class is P/F, then the appropriate schedule for you for first semester is that one semester Chem class with lab because it’s the only one that fits into the premed sequence and leads into Organic chem, the recommended French class that you tested into, since it will then satisfy your language requirement, (the farther away you get from French, the harder it will be, no matter what your past level of mastery of French has been), the P/F English overview class if it is mandatory for English majors, and a Freshman comp type class. That is 4.5 classes, only one science with lab (it has to be Chem first since Bio requires some Chem, and if you’re gonna bomb out on Chem, you need to know it asap and adjust your career goals accordingly), an easy for you French class, a writing class (your forte you say), and the P/F English overview class, which should be easy. That will leave you with some time for riding and research, and give you the best chance to get A’s in everything, but especially in the Chem class. But none of this is new. Every time you go back to advising, you seem to come out with yet another absolutely killer schedule that practically guarantees torpedoing your premed dreams, and that totally ignores your medical issues that make an absurdly heavy schedule even more inappropriate.
The reality is that you have a history of trouble with math. You did not do well on the Chem placement exam (and yes, I realize that you took Chem a couple of years ago, but so did almost every other entering student, and that doesn’t change the fact that right now your chem knowledge is not great in terms of being ready for college chem). The only non-subjective hard data point in your history that is completely independent of a classroom teacher’s subjective grading is a 1 on the AP lang exam (and you say that English is your best, easiest for you subject), and then you never took a standardized test again.
Please listen to reason and adjust your schedule accordingly. Your optimistic personality is a valuable trait, but when it leads you into accepting these ridiculously difficult schedules that advising keeps putting you into, it’s hurting you, rather than helping you. The schedule that advising has signed you up for is a recipe for disaster. You are adamant that medical school is the only career you want, is your dream. Please, give yourself your best chance of succeeding in achieving that dream by taking a reasonable first semester.
