<p>Engineers at Cal Poly don’t need any elective credit, there’s really no reason to take stats unless you just want to. </p>
<p>The first quarter of physics is really easy, I don’t know how the AP test is, but if it’s the same stuff as PHYS 141, I can’t see any reason not to take the test. </p>
<p>As far as graduating in four years, I’m not sure on the numbers, but I don’t know that many fifth year materials engineering seniors. Take from that what you will, but I don’t imagine it’d be too hard for you to graduate in four years, assuming you don’t fail a class or miss a prerequisite (happens more often than you’d think, the flowcharts don’t always show all the prerequisites, and teachers aren’t always willing to give permission numbers in that circumstance).</p>
