Was there a point to this?

Do you remember at school having to learn the collective nouns for groups of animals? Have you ever had to use any of them since?

We also had to learn weird units of measurement like; bushel, rod, furlong, gill, peck, fathom and chain. I remember tests where we were asked e.g. how many florins there were in so many guineas.  How many half crowns, three penny bits, farthings etc. Without a calculator, we had to rely on long division and then later, log tables. I wonder, do any of you recall how many yards there were in a mile.
