I need information in school?

my old school didnt have ipc so i am in 10th grade and taking chemistry. however, i moved and my current school has ipc a they say that chemistry is a junior cl, therefore since i am a sophmore they are making me take the biology taks test. but by may ill be moving back to my old school. my question is will they make me take both the chemistry and the biology taks this year. and if so if i fail the biology and p the chemistry will it matter because my old school doesnt even take the biology taks. helppppp
