On average, I would like to know how deeply some of the more mathematically inclined university students have delved into higher mathematics before attending university. I am in the top 5 for marks in my courses, but having talked to others in the top 5 I discovered that they had been doing the material covered in our courses many years prior to taking said courses. Am I at a disadvantage relative to those students even if our grades are the same? I only discovered the beauty of math at the beginning of the year. Is it too late to pursue attendance at a respectable graduate school given that I did not express an interest for mathematics prior to university? Please give me your thoughts and perhaps the level of mathematical knowledge you possessed before entering university.
