Here is my suggestion. Timing Groups in sequence so in levels and can grow and learn as a natural progression, 1 would be to separate time as an example- AM for all AI by level level 1 Ai - 6am, - level 2 Ai 7am, - level 3 Ai 8-am. M-f. Crypto Pm level 1, 1pm, level 2 2pm, level 3 3pm. M-f. Saturday Sunday and noon day for specials and promoting expansion and growth?
or switch crypto with Ai but group as not a staggered in learning and a natural growth patterns.
