Lessons for Violin

i’m need to learn how to play violin and i want to get good before school starts, so if you know an online website that I can use that would be great! Thanks!

Which should I learn to play? I cannot make up my mind.

I played all through High School but haven’t kept up with my lessons since then.

and also, am i too old to learn an instrument?

im 18 btw. i tried learning guitar by myself but i eventually gave up. now im planning to take violin lessons since im very interested in it. i also consider learning piano.

your answers, views and opinions are most welcome.

would it be hard for me to learn? How much do they generally cost?
tell me all there is to know about violin!
I really wanna play, it’s a beautiful instrument.
