Dear Friends,

I have programmed a CCS online workshop for USMLE 3 Exam Takers.
You will be required to register for CCS USMLE World or USMLE Consult.
I will be discussing selected high yield cases online, and shall provide you with Tips to Excel in the examination.

We shall be using Skype to discuss the cases. Charges would be $ 10 per hour, and the entire course would be about 20 hours.

Soon We are working on Podcasting the cases too.
