Hi aspirant.

As you may be knowing the cutoff differs each year and it depends upon various factors like the difficulty of the paper ,the specialisation,the number of seats available and so on. However according to previous year trends I can give you the last AIQ rank details for some Colleges in Tamilnadu for the general category:

MMC Chennai 

Obstetrics and gynaecology -1331

Surgery 1258

Ophthalmology 1438

Anaesthesiology 3145

Stanley Medical College Chennai 

General medicine 462

Surgery 1326

Ophthalmology 2446

Hope this helps.

Good luck!!
