A community of 30,000 US Transcriptionist serving Medical Transcription Industry
I took a test for an MTSO last week that required extensive knowledge of prefixes, roots, and suffixes. I found an online resource that resulted in my getting 100% on all 4 sections of the test. I have to admit that I knew probably 75% of them, but this resource helped me pass all of the tests.

However, I haven't heard anything from the company other than "Congratulations! You passed all 4 tests 100%!" No actual transcribing test yet.
