One option would be to go through the other Fundamentals 1 courses. There are three tracks available, and each is slightly different with good tips and tricks.

That being said, I went through the same decision recently. My left hand is not up to par with where I wanted it to be, despite hours and hours of daily practice. I was getting bored with that, so I moved on to Fundamentals 2. I have not yet hit a lesson that I should not be attempting with my current skill level, and it feels good to progress.
