“Since colleges like 4 yr math, 4 yr science, 4 yr foreign language, 4 yr history, 4 yr english” If I understand, your student already has 5 years of high school science including 2 AP classes. While it seems to have been a bad idea for this student to take 3 science classes in the same year, I don’t see any deficiency that would require taking yet more science senior year if there are options the student prefers. Is the admissions office telling you this? To me it seems like it may be a good idea just to prove that the student can do well in an AP science class. But I don’t see how a college would expect 6 science classes.
