The school I went to (all west/select sires) was a full week. 5 full days of school, half of the day was in a classroom, the other was working on live cattle. Part of the classroom work was using dead repro tracts which was the best way (in my opinion) to get the idea from bookwork to live cows.
When you inrole they should give you a list of things to bring. I also recomend a pair of clamps (to hold your glove to your coveralls) which wasn't on my list of things to bring, but I wish I had every day of class! I know with a full week of live cattle, I wish I had a shoulder cover also! Your coveralls get mighty nasty. Just some recomendations. Breeding your own cattle is very rewarding!
Best of luck!
