Depends on the HS and the competition for roster spots.
HS is not a great test as the level of play has huge differences. You could be the best player on a small 1a HS and you couldn't be the bat boy on a top 5a.
You can have a great experience in travel BB and you could have a bad one. At college it is the same except the players are the best ones from all the HSs. That is really when you start to see if you stack up.
