School I teach in has two LC Physics classes, 2 LC Chemistry classes and 3 LB Bio glasses as well as 2 applied maths classes and LC PE.
There’s a lot of crossover with geography, even with some of the physics students so it’s a non runner.
There can’t be any clashes
I'm going to take a wild guess that the numbers taking home economics and DCG probably don't overlap too much. Wouldn't be too hard to pick subjects with small number of overlapping students to try and get two subjects done on some days, if the current proposal is to have only one exam per day.
