Thinking Of Becoming A Medical Transcriptionist

Now that my ongoing online job will end in about a week or two’s time.  I am thinking of taking an education that would make me become a Medical Transcriptionist.  Since I have a pre-med course, I am qualified to take the short course which is 3 months.  I am hoping I can have a work-at-home job just like the one that I have now because I would not want to go back to the corporatr world. 

Anyways, I am looking for an online tutorial on medical transcriptionist so I would not have to leave home while studying.
