Math CST question!!!!! 9TH GRADE?

hi im a 9th grader, and i am at algebra 1 class, anyways i want to ask something about my math CST ,i took a math cst yesterday and most of it was from the first semester, and i wasnt at usa the first semester, but i was learning math from other countries, so i didnt answer most of them, because i wasn't there the first semester, do the people who are gonna check my scores know that i was absent the first semester? , because its not my fault that i was absent.So are they gonan notice and do seomthing about it, or they wont care and just put my grade? Thanks
