Hello Pavankumar Sooreddy. Thanks for contacting Careers360 and we hope we will be able to answer your query.

As I have answered in an earlier question of yours, you can definitely apply to colleges in Tamilnadu through Anna University's other state quota. 

The cutoffs for the TN state board are generally calculated as follows (all marks are out of 200):

• Cutoff:= (Maths marks)/2 + (Physics marks + Chemistry marks)/2

I would advice you to convert your marks to 200 and calculate the cutoff on this basis. Hope this helps you and all the best!
