Which score is a better indicator?

Test Preparation
1

<p>So I took a mock SAT from Princeton Review and scored a 2100. I was pretty satisfied since I did not study yet…</p>

<p>But then I got back my psat scores back and I only got a 190. When I looked at my mistakes, I was kind of mad at how many stupid mistakes I made and I felt like this was a one time thing. But due to the whole hindsight bias phenomenon, I can’t really trust myself haha.</p>

<p>So, I want to get a good idea of how much I need to study. Which do you think is a better indicator? A psat or a mock Princeton review SAT?</p>

<p>Thanks guys.</p>

<p>In general I’d say PSAT just because it is taken in the same environment as SAT. But the stupid mistakes thing is probably legit; scores vary incredibly just depending on how acute/focused you happened to be at the time</p>
