PSAT Score Corresponding to Actual SAT Score?

<p>I got an unusually low score on my practice PSAT. I’m not sure if it had to do with me rushing to finish the test (most of the errors I made were in the last two sections after I resumed the test when I got home), but I scored a 191. The last practice SAT test I took, I scored a 2020.</p>

<p>Are the PSATs a good indicator of an actual SAT score?</p>
