<p>I am not sure, so don’t take my word for it, but I would just send all of them. I assume they are like other colleges and pick what makes you look best. Plus, they can see your improvement.</p>
<p>SEND ALL! According to collegeboard, Cal Poly superscore (use highest section across all sittings at least for SAT). Not sure how they treat ACT and whether mix SAT & ACT</p>
<p>So at least you would have CR:630/M:640(SAT) and English:28/Math:32(ACT)</p>
