I don’t see trigonometry or precalculus on your list. Universities can teach you calculus, but the prerequisites for calculus are likely to be expected for admissions to top schools. Statistics is likely to be useful for someone majoring in sociology.
Did you take any foreign language, or any language other than English? (I am not sure if Spanish really should count as “foreign” for someone from Texas).
Do you have all A’s throughout high school? If not, then how how many A’s and how many B’s do you have?
Do you know any French at all? It is not needed for McGill, but might be useful to have some fun in Montreal. I am pretty sure that you could learn this after arriving in Montreal (for example they could probably match you with an intensive immersion course over the summer).
