Please help - confused about which ACT scores to convert to SAT for MCA scoring

Older son took ACT twice. We are trying to figure out what score to use to convert to SAT so we can calculate his MCA. Here are his two test scores:

English 36
Math 30
Reading 31
Science 33

English 34
Math 34
Reading 32
Science 35

I know Cal Poly superscores - do I take 36 for English and 34 for Math for a composite of 35, which we can then convert to SAT? Thank you in advance!

Okay, in reading other threads, it looks like it’s Math and Reading, not Math and English. So would we take 34 math and 32 reading to get composite score of 33, then convert to SAT? Thanks!

I’m pretty sure it’s actually Math and English for the ACT. @Gumbymom, do you remember?

Just called Cal Poly, it is Math and English (for which I’m grateful!)
