Grade_01_What songs did you aspire to play when consolidation grade 01

I have been in the consolidation phase of Grade 1 for the past three weeks. Progress has been steady, albeit at a slow pace, which is ok. I would like to hear from those who have completed Grade 1 about their experiences with Justin’s Songs app. Which songs did you aspire to play by the end of Grade 1? Additionally, which songs did you find to be the most challenging when filtered by Grade 1 level?
