Idk what u r studying  but I'm in my last year in high school and I'm learning Arabic and it really help if you could choose Arabic as ur mother language you should ask the school about the Arabic classes which many schools have so you could learn the grammars and meet the other Arabic students I hope this was helpful

اكتب على برنامج الامازون كتب تعلم العربية واذا اردت سأقوم بمساعدتك

Probably best to start with www.arabicpod.net as it will cover all three of these, gentley.
