in the high school game the clock is stopped for goal, injury penalty kicks and any cards given, and also may be stop on substitutions if the refree thinks the winning team is substituting to stall. the rule of adding time is fifa.
goalkeepers may bounce the ball as long as it is possesion and has 6 seconds to get rid of it.
offsides is a different animal in its self. most fans are watching the game (which means the ball) they have no idea where the players were when it was kicked, you have one set of fans yelling offsides and the other set saying it was alright. in my opinion the refs get the call right 95% of the time. nobody is perfect and no teams are perfect, but everyone wants to lay the blame on the officials. I never see on here where an open shot was missed that cost a team the game. or that the defense had a break down. Eveyone wants to blame it on a call. So everyone needs to remember that most of the officials do the best they can, and yes they will miss some, but hey what about praise when they get them right.
