Many districts are cash strapped (were down to 4 days a week not long ago) and only regents requirements were taught. Reducing the mandatory classes means you allow for districts to cut some classes with no consequences - it means that in poorer districts there won’t be any chemistry nor any physics anymore. In order to attend KU students will have to take science classes after Biology but each school will be free to decides what counts. In fact the 4 directionals will no longer have any course requirements just a 3.25 GPA.
