Just learn etude no 1 from today for this week. Add bass drum on every beat if you can. Try to play it like a performance, I want to hear it top to bottom next week. I think 120 should be a reasonable tempo for you but faster or slightly slower is fine.
Good work today! Try to make some progress on “drum corps on parade” on your own so that we’re actually getting somewhere with it. It should be doable for you within a month. Let me know if you want to do more xylo in lessons or if you have some other way to work on your reading abilities for pitch; if you plan to do keyboard at any point in your life it’s definitely best to start asap. Keep up your own practice on kit for band rep obviously but we’ll try to get through some more solos and etudes in future lessons.
