As always, I'm going to try and convince you to go back over old lessons - we have covered such a vast amount of material, it's highly doubtful you remember how to play everything we've learned (c'mon... do you mean to tell me you got PERFECT in the chord quiz?!) After you've done that, you can focus on the following:

• First, make sure your guitar is in tune.
• Download one of the software versions of a metronome, and use it to practice with.
• Practice scales we've learned, using the metronome to keep time. Try palm muting the scale. Try sliding from note to note. Try hammering on as you ascend the scale, and pulling off as you descend.
• Practice this lesson's major chord inversions. We're going to keep studying these in detail, so it's important to get these basics together.
• Do some string bending. Do this often, because you won't get better at it until you build up some finger strength. Even if you hate doing it, try doing it for one or two minutes every time you play guitar. You'll be happy you did.
• Keep practicing the fingerpicking patterns from lesson seven and lesson eight. We're going to keep learning fingerpicking patterns in upcoming lessons, so all those we've learned are extremely important.
• Try to play all of the songs above, plus keep playing those from previous lessons.
