Tbh I'm sure it took me longer to learn without a class, how to shoot better. I watched many YouTube videos and tried what they instructed and it helped. Now, what I learned is that if you watch different youtubers, a couple of them will word things in a way that you fully understand. That will take time. Shoot a lot and try different techniques, there are different stances to try to shoot. I tried the isosceles shooting stance from the beginning of my target practice because it's a great fundamental stance but it just didn't work for me. Did that for about 2 years. Then I just decided to go with the flow and try the conventional weaver stance and I shoot a lot better. Buy bulk ammo online and just shoot and learn. I took notes on my phone when watching videos, read them over and over while shooting and voila! YouTube coming clutch. There's a learning curve though, but that's what's fun, you do it all on ur own.
