Both have added value. SGA or any extra curricular activity will diversify your resume and will show that you are an active member in your high school community. It will teach you life skills, such as time management, that cannot necessarily be learned in a classroom. However, if you're already very involved in your school, I would recommend taking an AP class. It will better prepare you for the study time needed in college classes. And assuming you pass the exam, you will probably get college credit for the class. If you know where you are going, check to see if the AP class will count for college credit so you don't have to take the class again.
Lauren recommends the following next steps:
- talk to your guidance counselor
- look for other ways to get involved aside from SGA
- see what classes best fit into your schedule
