For an application to a university, do you need extracurricular activities?
I could not do any extracurricular activities due to transportation, but I heard universities are mainly looking for students who do them. Will that impact my chances of being accepted to a good university?
It does help with your acceptance into college. Excellent grades and competitive SAT or ACT helps too along with letter of recommendations from your teachers. Have you thought about volunteering within your community or church? Do you have a part-time job or do you baby sit for friends and family? These count too!!
With transportation being an issue, would it be possible to get a ride from another student to participate in a school extracurricular activity? It never hurts to ask. You may want to discuss your participation in a school extracurricular activity with your counselor to see if they can help you attend.
Joining a school doesn't always require it, but if you're aiming to lead a program, having it can be fantastic for your future. Keep things simple and stay motivated!
It's great that you're thinking about this important topic as you get ready for University or College. You're right, both higher education institutions and future employers usually appreciate the involvement in extracurricular activities. These can involve being a member of various clubs, participating in volunteer work at school or in your community, and having part-time jobs during your high school years.
I trust that this information has been helpful, and I'm rooting for your success.
That being said, it helps to stand out in comparison to other students, where you can say "I did/achieved so and so." For example, I had taken many college-level courses in high school and had good experience in computer programming, which would be my ultimate degree. That doesn't necessarily mean academic achievements*; I recall reading that someone had gotten into a pretty good college for writing a novel (unpublished or published, can't say) during high school.
* I don't know much about the admissions process, as a note.
