Hi,

As far as I can conclude, I think you are from GM category. Now, if you have studied in a school where the medium of teaching was Kannada then you are from GMK category. If you are from the Brahmin caste, then you are from G1 category but if you have studied in a school which is English medium then you are from GM category but if you have studied in English medium but you are a Brahmin, then you are from G1 category.

Hope this helps.
