For a child who has no plans to go to college is it a bad idea to not do the traditional highschool full year courses of chemistry, biology, physics? He already has a credit for Physical Science. My thoughts to replace it are to have him do a very light course in Chemistry and Physics to learn the basics- for example about a 1/2 credit worth of each, possibly a full year of Biology, and use the remaining time to due more interest based subjects such as an electronic course, animal health, small engine maintenance etc. Would there be any negatives to this? Could these count as science credits?
