OnExamination : The Password to Medical Exams

I have just gotten to know about this very useful webside called OnExamination which is very useful for exam revisions. They provide online revision courses for medical exams, such as MRCP, MRCOG, MRCS, MRCPCH, MRCGP, GPVTS and Medical Student Finals
I am currently trying out their MRCGP revision course that they have graciously allowed me to try for 2 months.
The site is very well organised and is certainly worth checking out as a very useful resource for doctors and health workers.
