i need help with scribie

I've applied on scribie, a website where you transcribe audio files, mostly interviews, and you get paid for it. I received a notification already that I can take the test. All accepted applicants are required to transcribe one test file, this will determine if you'll be come a transcribe for scribie or not. I've already tried taking the test twice, but had to cancel both times because the audio quality is just too bad. I want to know from people who were able to work here (scribie), is it really this hard? Can you give me any tips on how I can pass the test? Thanks, any input will be much appreciated.
