Drivers ed driving test?

Exactly how hard is the actual driving test? like how picky are they? Im pretty good at driving considering I used to park cars at an impound business my dad owns. and I 80% of the driving i've done was in MINNESOTA snow (10+ feet tall snow banks on the edge of the roads). I once did a corner that had ice and slush on it that everyone was spinning out on and I was the only one not to.
