Hello. I was told that it is ok to cross-reference TWO or more courses from different periods, as long as these courses are of the same level. For example, I went ahead and cross-referenced ("combined") Periods 2 and 6 of the Orchestra
QUESTION: would it be ok if I cross-referenced ("combined") TWO different level classes that meet during the same class period, i.e. cross-reference 01-Orchestra 2 and 01-Orchestra 3 (period 1 orchestras 2 and 3)? Image is attached.
