When i'm taking the math portion of the SAT am I graded on my answering method and answer sheet?

Hi,

When i'm taking the math portion of the SAT am I graded on my answering method and answer sheet? 

I have been studying abroad for the past several years and we were graded in that format, so even if you answered the question correctly but your method was flawed or had a mistake you still lost some points for that.

I am curious to know if it works in the same way.

Thanks in advance *^_^*
