<p>Actually, if you look at Table II-3 in your own document you will see that the average GPA rises from a 2.8 freshman year to a 3.1 sophomore year, 3.2 junior year and 3.3 senior year. The average GPA in the science classes is actually lower. Hardly a case for grade inflation especially considering the level of the entering class. If anything things have gotten tougher not easier in the past few years. P/F is only first semester freshman year, second semester is A/B/C/NR.</p>
