<p>Which Cal Poly? SLO does not have chemical engineering. Pomona does. Pomona also has a four year graduation pledge, where you agree to follow your major’s course plan, not change majors, and not need remedial courses, and they will facilitate registering for courses to graduate in four years: [Graduation</a> Pledge | Academic Programs | Cal Poly Pomona](<a href=“http://www.csupomona.edu/~academic/programs/grad_pledge/index.shtml]Graduation”>http://www.csupomona.edu/~academic/programs/grad_pledge/index.shtml) . However, Pomona is widely considered to be more of a commuter school and is not as well known as SLO.</p>
<p>Regarding GPA calculation, all California publics (including the Cal Polys) recalculate GPA without 9th grade course grades (although 9th grade course grades need to be C or higher for the courses to count as courses taken).</p>
