SAT II Chem score from June went up last week!!!

<p>I was looking at collegeboard.com last week.Noticed my score in Chem SAT II went up all by itself. I called and they said that they just changed about 4,500 out of some 34,000 Chem test. Apparently, there was a grading error. Anybody else have this happen??</p>

<p>really? thats cool! (how much did it go up by? )is that only for June ones?</p>
