<p>I think you’ll want to stress that it was volunteer but I also think you might want to find something charitable that you’re interested in and devote some hours to it. I’m not sure about the ACT but I’ve heard a lot of people mention retaking it while in college so I guess it can be done. Notre Dame seems to put a lot of weight on high school performance and test scores even though you’ve clearly proven your ability in college. If you can’t retake the test, I would do something to make myself stand out. Like I said, there seems to be a lot of impressive transfer applicants and the pool is getting more competitive so it wouldn’t hurt to stand out. </p>
