It's definitely GOOD the real question is it worth all money you pay for it. Now I don't know first hand, never been but your in luck. My man Charles has and he has a youtube and he's cool dude and he has a rocking beard! Heres his chan. He's very knowledgeable about cars, specializes in VW's and you can ask him questions like Scotty and every once in a while he'll do a mailbag episode and pick your question if your lucky.

In this list above I would watch the first and second video skip the third watch the fourth, the 5th is optional/save it till end if you want to watch it. Definitely watch 6th and 7th video before that one. 

And that should catch you up to roughly today and then the last thing from me is school is great and all but nothing is gonna beat hands on experience. If you're dead set on being a mechanic realize 2 things. We are swifty making a move to electric vehicles so Scotty recommends you learn about them because they're super dangerous to work on and 2 get yourself a turbo beater car for >1000$ the cheaper the better and the more problems with the car the better and try an older car like 2003-5ish dont go too old because it won't be what you'd likely work on after school and start small. Do some basics repairs and as you learn apply that to your "test car". Then if you mess anything up who cares because its not actually your car that you daily and then maybe you turn that car into something that runs and drives eventually and sell it and get another nugget car and fix her up again(or get a job fixing nuggets either way)

GL future mechanics we desperately need good ones because there's a LOT of bad ones lol
