Can I take the california cst at home?

The cst is coming up in california. I'm homeschooled. The school is now telling me I have to take the cst at school. But the problem is if I go to the school all the students will ask me where have I been and all of that and I'm to embarrased to say I'm being homeschooled. I also get anxiety attacks entering the school. The reason I'm being homeschooled is because I was bullied a lot in school. So if I got to school to take the test my bullies will most likely target me. I want to know if there is a way to take the cst at home. I'm a 14 year old 8th grader in a lynwood county school in LA. Please I don't want to return there! Is it possible to take the cst at a local library or something!
