Dear Jagadeesh, 

Yes you will have to appear for MCI Screening Test. However, if you would not have to appear and qualify for the screening test, if you completed MBBS from any of the countries, i.e. Australia, Canada, New Zealand, UK or USA, and have completed PG medical qualification in any of these countries and have got the license to practice as a medical practitioner in any of these countries. 

Hope it clears. 

All the best!
