This was given to a student to help them see more of the fretboard by using some fairly simple shapes/patterns that ascends three octaves. 

You COULD say four octaves because of the fourth A note you finish on, but the pattern being used is only in three octaves.

If something like this feels difficult at first, it's a good idea to break this down into smaller pieces. Instead of trying everything, try one bar at a time until your fingers feel comfortable with the pattern. Try each bar individually too. Then, once each bar is feel comfortable, try two bars at a time. After two bars at a time feel comfortable, go back to trying the whole thing!

Here's a challenging yet fun scale run/lick to add to your shred guitar tool kit!

All of the odd number bars play two groups of sixes, and all of the even number bars have you run up or down notes one after the next. 

Most likely, the even numbers bars will prove to be the most challenging.

If you'd like practice advice on how to push something like this to the max, there's a free eBook I put out called the Metronome Method, and the principles taught are how I got this lick up to 300 bpm, as shown at the start of the video in this post.
