I'm 16 years old and I'm starting my last year of high school in about 2.5 weeks. I've managed to get in all the courses I need to go on throughout this path in College and University. The only thing is I'm not getting 90's in those courses so it's making me nervous because I see people who are already getting those marks. So i'm wondering about something: Can I manage to get all my marks up to 90's within this last year so that I have an average over 90 by next June? It's just nerves because there's people around me who are already so smart and I'm wondering if I can make it to even pass their level because I want this so badly and the only thing that keeps pushing me every once in awhile is if it'll be worth it to study this because I might not be smart enough. Right now my overall average is 80-82%....Is there any hope? Thank You!
