Answer:
I am basing this answer on the assumption that your school does not have a very large selection of subjects.
Dual Credit Core Subjects: allows free college credits in high school
Architecture/ Video Game Design/ Technologies: can give accreditations in designing software
Choir/ Band/ Theatre/ JROTC: Helps make better friendship and connections
Language Courses: Latin, Spanish, German, French, etc.
You can look at your school's course selection versus others by other's too get a better idea.
