One should ideally prepare for MCI screening test starting from 2nd year of MBBS and not after coming back to India. Kindly go through the note prepared for the FMGE –
In any case, if you have not prepared, you can start the same at DIAMS, New Delhi ( )
You must also prepare for MD abroad at the same time, so that, in case you are not able to pass through the MCI screening test, you are well in time for MD abroad in locations like Germany and USA.
Best of luck!!
