Hi aspirant,

You scored 115 marks in nata. Your 2nd puc percentage is 73. You asked if you may get a good seat in Karnataka.

Now, see,

With 160+, one may get a good government seat

With 130-160, one may get a descent private seat

With 110-130, one may get a private seat

So, you may get a private college obviously. You may get also a top level private  college but chances are less.

All the best  !!

:)
