Is it possible to get more than the required amount of credits? (In High School) How?

Wow, that's a lot of credits. In my high school I get 1 credit per 1 class per semester, so a 2 semester class would be worth 2 credits. Take electives (optional classes such as French, German, Band, Art, etc.) to get more credits. Fill in your spares with electives to get more credits. It is very easy to get more than the required amount of credits if you take no spares and fill them with electives. So yes, it is quite possible.
