Hello Aspirant,
The total marks in Kerala State 12th for 6 subjects would be 1200 . So in order ti score 95 percentage marks out of 1200 , you will need 1140 . So on an equal distribution basis , in all your subjects if you manage to score 190 and above out of 200 , then you will surely get 95% and above. 190*6=1140 and 1140/1200*100=95.
So prepare very well for all your subjects . Looks like you are very determined and focused about scoring well in plus two but in case you score a little less than what you expected , there is nothing to be disappointed about . 12 marks will follow you only to a certain period , basically until you get into a decent college for your desired course . After that it is you interest , hard work and passion towards your chosen field that will help in the long run.
Hope this helps
All the very best
