Let me tell you exactly what you're up against.

The university I had attended had roughly 300-400 ambitious students wanting to get in to the program.  The bar to get in was not high for university standards (eg. 80%+ high school), no portfolio or much prior knowledge.  It was not a competition of peers, but based on your own abilities.

If you manage to figure out the first year, which about 30-40% did, and did not deviate into mathematics, business, or other unrelated disciplines, you're up for at least another 3 years of late-night puzzle solving.  Each year, the same percentage would drop out for their own reasons.  This was not about studying longer, but your ability to solve deep problems.

At graduation, there were about 30 left which managed to accumulate enough credits in 4 years.  Most of the challenges lie in the specific challenging and required courses. 

Simply put, eagerness and endurance isn't enough.  Ready to almost lose your minds?  Is it the career for you? Maybe..
