SAT curve 轶事：1994全年只有25个SAT满分，curve放宽后1995年4月的SAT考试一下子就有137个满分。
"Beginning with the test administered in April 1995, the SAT score scale was recentered to return the average math and verbal scores close to 500. Although only 25 students had received perfect scores of 1600 in all of 1994, 137 students taking the April test scored a 1600.[63] The new scale used a reference group of about one million seniors in the class of 1990: the scale was designed so that the SAT scores of this cohort would have a mean of 500 and a standard deviation of 110. Because the new scale would not be directly comparable to the old scale, scores awarded on April 1995 and later were officially reported with an "R" (for example, "560R") to reflect the change in scale, a practice that was continued until 2001.[54] Scores awarded before April 1995 may be compared to those on the recentered scale by using official College Board tables. For example, verbal and math scores of 500 received before 1995 correspond to scores of 580 and 520, respectively, on the 1995 scale.[64]"
