Just a minor point. She doesn't know everything about Norn Weaponsmithing nor Char Weaponsmithing. She learned everything she cared to know about both (though I think in the Carr case it was actually demolitions and not weaponsmithing) which is very different than learning everything about them. She learned what she thoughts was important and nothing else. Which could potentially be her downfall. Often it ends up being the things which objectively seem unimportant which end up being a huge deal.
Also she just graduated from the first two colleges in record time. She struggled with the third quite a bit and her thesis she presented to that college was rejected and as a result she joined the Inquest.
