The fact that the chords are all (a) in root position, (b) in the treble clef, (c) in close voicings, (d) only built on naturals, and (e) unaffected by key signatures definitely makes things easier: give me a series of spread voicings scattered across the grand staff in hard key signatures with inversions and accidentals thrown in, and I guarantee you would absolutely trounce me.

I would be trounced by that as well I think😞 at least if it was timed and I did not have access to a piano. Also in that case you would need the key and chordal context to accurately name the chord as the same notes are different chords in different contexts.

I also really wish that toneGym would change the key signatures sometimes...

Though I can say for a fact the the number of people who are able to get a score over thirty on this one is pretty low, as it requires knowing the scale degrees of each chord and the treble clef inside and out. It is not as hard as it could be, Thankfully! So good to be humble, but also recognize that that is a really good score for this one!
