Edward, I can help you if you want to try what I do for a fingering exercise, and I just do it to get my fingers warmed up for the lesson or song to come. Using all four fingers, I set the metronome to 160 for me. You might start at 120, and play all strings up the neck to the 12th fret. Then I use three fingers and do the same thing. Then I do two fingers the index and third, and then also the second and pinky. If you get really daring you can also set the metronome to give you speed drills. Hope this helps.
