It sounds like that's what the school typically offers for coursework at that grade level. I think they are doing one subject a day because the regional public health guidance requires fairly strict cohorting, and this provides maximum flexibility for scheduling every student into the classes appropriate to them. If you offer two or more classes a day, you have to find a way to arrange every student in the school into a matched set of classmates with very nearly the same schedule of courses for the year.
In any case, I think Wren's regional guidance just changed, so it could all change tomorrow.
