21 Day Challenge Success Stories

Shemar Hill R.T. (R), The Comeback Kid

After a devastating knee injury and two failed ARRT® exam attempts (58 and 64), Shemar was one test away from losing it all. The pressure was real—and the stakes were high. But then he found the 21 Day Registry Review Challenge.

With expert support, structure, and a like-minded study community, Shemar turned everything around. Just weeks later, he walked into the testing center one final time… and walked out with an 84.

His story is one of grit, growth, and never giving up.
