Is there a way to take more courses?

i am in 10th grade and our school has 6 cles....i want to take more cles cuz with 6 cles i can only tak the basic cles so i am wondering if there is a way for a tenth grader to take extra cles like night cles like adults do (if high schoolers can) or another way besides goin to a college cuz we cant take college classes until 11th and 12th grade...i just want to know if there is a way to take like 1 or 2 extra classes a during the school day so i would be taking 7 or 8 instead of 6....
