I see on yours. Maybe I was reading this one wrong?
It shows a dark period is capacity constrained in the legend and Chem was noted. But I see on the others it isn’t.
That might be a good 1-2 then - biochem (if the top choice) as the 1st major and Chem as the alternate - to give the OP the best odds.
I guess I’d say likely then (at least in my opinion).
Anyway, this is the link I saw it on but if I misread, I apologize.
