It was great having you as a student. Here are some recommendations and things you can work on at home:
-Essential Elements book (you can order a CD with accompaniments, check the attachment at the beginning of the book for info)
-Major and minor scales and arpeggios
-Practicing steady long notes with a tuner is very important for getting a nice sound and playing in tune
-After figuring out the notes and rhythms of a particular passage or exercise practice it slowly with a metronome and speed it up as you feel comfortable.
I wish you well in all your future endeavors,
P.S. Thanks for the gift card!
