Actually Synthia that IS true in MOST cases, but there are SOME schools that offer summer courses for other special reasons...For example if they are just now including a new subject into the curriculumn; sometimes they offer classes during the summer before as a test to see how well the students will take to them, and whether or not there are any bumps that need to be ironed out. Another reason; in the case of gym for example; is modesty reasons. The public high school here in Bryan offers gym classes during the summer because some people feel too uncomfortable taking group showers; guys and girls. My son will be entering high school this next year in Bryan, and because he does feel uncomfortable like that we did sign him up for the summer gym class which will count for credits for his first year there...
