[DnD] I'm first in my wizarding school and this dork who could barely cast a cantrip took a summer job with a bunch of adventure types and came back and is now the most powerful wizard in the city what gives?

You learned in a controlled environment where your teachers gave you new material when they felt you *were* ready. 

The "Dork" risked his life, and had to *be* ready. Believe it or not, change changes people. Plus, delving into ancient tombs and fighting other mages is an *excellent* way to find old spell scrolls you can copy into your book.
