Given that there are not too many one chord songs, this won't be the most rewarding moment of the course! However, that's okay because good things come to those who wait, and I won't make you wait too much longer! Nevertheless, if you can sing a melody while strumming the A chord, you'll start to hear the musicality of what you have already learned.
I have heard how giving you are in so many respects of music schooling and I must say that I am impressed. You remind me of the pure idealism that we had in starting Apple. If I were young, with time, I'd likely offer to join and help you in your endeavours. Keep making people happy, not just in their own learning, but in the example you set for them. 
Some instructors spend too much time talking about theory and other things mixed right in with the middle of the song instruction, irrelevant to actually learning the song, and then fly way to rapidly though the chords, progressions and riffs, making learning difficult and multiple rewinds and replays necessary.

The distance from the top of fret to the bottom of the string should be no more than three times. If it is five times, the guitar may have a warped neck or too high of a bridge.
