hello,

With 159 marks, even under the SC category, unfortunately, you do not stand a chance of admission. The cut off for the SC category in Karnataka the scores are above 450 . You can check them here if you want:

You can always drop a year if you are passionate enough for this stream. Otherwise, there are always other streams you could go for.

Hope this helped. good luck for your future!!
