A study was made of the gains in physics achieved by different groups. Those who presented high school credit in physics for college entrance made a greater average gain than those who did not, but a smaller percentage of gain. Those whose intelligence rating was in the upper fifty percentile made a greater gain than those in the lower fifty percentile, but a smaller percentage of gain.
