ACT test time taken reporting on CA

I’ve taken ACT 4 times. I self report my ACT score on common app, combining the scores from two tests. In this case, in the section of the number of testing, should I write 4? or 2? I’m not gonna report any score from the other 2 times, and my applying school does not require all test scores reported; they say they’re gonna superscore regardless of dest date

You do not combine the ACT scores. You will list each sitting separately and then send the official score report to your schools of interest. The schools will superscore the ACT, not you.
