Yea that's extremely good! I just graduated high school in 2007 and I took the ACT about 5 times while I was in high school starting when I was a freshmen. The first time I took the ACT I made a 19 and from there on it kept increasing the more I took the test. The second time I think I made a 21, third time like a 25, fourth time I made the same, and the fifth time I made a freakin 27!! So I encourage you to take the ACT as many times as you can because it really helps to get the hang of standardized tests. I currently go to a large university with a full-paid scholarship so the higher you make on your ACT the higher chances you have in earning a full scholarship! Good luck!!! Hopefully by the time you are a Senior you will be in the 30's!!!
