Different curves for different versions of the same test?

<p>I was wondering if there are different curves for different versions of the same test. I got -2 on the multiple choice and an 11 essay and got a 780, while someone I know got -2 and an 11 and got an 800. When I reviewed it with this person, we noticed that I had different numbers of difficult/easy/medium questions than he did. Just wondering if our different scores are because maybe we had different versions of the test (we both took in November btw).</p>

<p>there were 2 versions of the november test. one was much harder than the other - i got -1+10E for a 800.</p>
