“As long as you got over 75% and you’re confident that you’re not getting one answer consistently wrong (if you are, study that interval more!) you’re ready to level up!”
100% on the quiz. Easy-breezy.
But “eeeerrrrrrrk”, (sound of record needle scratching across vinyl) there is no level to “level up” to. 
More on that at the end of the Grade 3 discussion. I’ll make suggestions. I still have work to do. I’ve got the sound of the notes down solid, but? Practice makes permanent.
I’m going to go back and spend more time on Mental Fretboard Development.
That has a couple (or more) purposes.
- Visualizing the fretboard
- Pairing fretboard visualization to mentally constructing sound
- Working on I-IV-V chord progressions, determining the key, then determining a random set of notes of that key and find them on the fretboard.
I’ve got a lot of room for work on fretboard memorization, fretboard note visualization, and mental audibilization of scale degrees, and chords, and progressions. Onwards and upwards! 
And I need to do the Quick-Fire Quiz, but I’m not too worried.
