<p>The LSAC will inform law schools what the average GPA at your school is to help them make the comparison.</p>
<p>Correct me if I’m wrong, but my general impression is that law schools do not usually consider this information with any great weight.</p>
<p>Finally, while this is unfair, this is not an unfairness that is perpetrated by the LSAC. It would be vastly more unfair for them to make up grades to give you. (By, for example, assuming that 1/3 of your A’s were actually A+'s.) Many of the corrections they could possibly make would have to implicitly assume something like this.</p>
