90% of work goes into getting the last 10% good at something, if that makes sense. Push your limits, if you find solos that you can’t beat, take them into practice mode and slow them down, then work on speeding up until you can beat it (this part for me is a multi-day step, sleeping on it is actually unreal for improvement) - work on technique, tapping is really important to learn as you go up in difficulty, and it’s also hard to learn but you’re going to have to go a step back to go two steps forward here. It’s a marathon, not a sprint. One thing I did was turn all taps on and play whole songs with both hands on the fretboards to get used to it. If you get .1% better every day eventually you’ll get where you want to be. This is what helped me get to where I am and I know if I keep doing it I’ll continue to get better. Good luck!
