Great to see your progress Steve.
Back in November, we discussed that we were both working on grade 3 and wanted to keep our motivation as high as possible. So, I’m really happy to see that we both successfully achieved our goals. 
On a positive note, the step between grade 3 and grade 4 appears smaller than I anticipated. So, that’s a good news for us.
It’s probably due to the 6 months consolidation that I did learning the first 10 songs in the JustinGuitar Rock Songbook which were ranging from grades 2 to 5.
Your consolidation plans seem similar so I’m pretty sure it will give good results. Grade 4 is a lot of fun, even more if you enjoy Blues.
