Missing the SAT?

My state is requiring all juniors to take the new SAT this March. My school is holding the SAT during school in a few weeks. The issue is that they aren’t offering the writing section, and all the schools I am applying to require the writing section. I just took the “old” SAT this past weekend (with writing), and I don’t want to take the new one especially because I’d have to take it somewhere else with the writing if I wanted to use that test for colleges. What would happen if I didn’t show up to school that day to take the SAT? I wouldn’t get a 0, would I? I’m guessing that whatever happens would be similar to if I didn’t go to a regular SAT that I had signed up for. Does anyone know how that “normally” works?
