How much shit you "learned" in indergead did you actually retain?
I is right next to U and my hands are freezing. Chill
90% of it I'd say I retained very well.
10% of it are like... tools that are never used. I remember that they exist, but it's been so long I'd have to practise with them before they're useful again. But, undergrad exposed me to those tools existing, so they're still part of my toolkit (even if they're dusty).
