Has any1 taken the ap calculus exam or will take it? i have a question!?

I know that if u omit a multiple choice q, u dont get any points off. Does the same go for the 6 free response questions? Like if i omit 1a and b, will i get penalized? And also someone told me that if u get the free response wrong, you still dont get points off. Is this true? is the only way to lose points if u get a multiple choice wrong? thanks
