Of course it will be detrimental. It is not going to improve your chances. An A or B would be much better. Isn't that the obvious answer. Should you give up on getting admitted to USMA, of course not. Work hard, get better grades and continue with your EAs.I am a sophomore in High School and I am taking honors class and planning on taking on some AP classes next year. Would a C in an Honors Chemistry course be detrimental to my résumé?
