<p>Our state requires four years of math, science, social studies and English in order to graduate from high school. There aren’t a lot of slots in summer school classes, so most of the teachers have to grade so that almost everyone passes each of these classes. Way too many problems would be created if more than a few students failed required courses. But in college, no such problem…a student washes out a Duke or University of Texas…there are multiple students in line to take his place.</p>
