Hello studnet,

As you have mentioned that you have 42 percent marks in your boards with biology stream.

As intermediate marks are not a big deal now a days as if many of the college takes admission on the basis of the score in partucular entrance exam.

On the other hand if you want to join some institute directly then you can go for some good deemed universities too.

So don't lose hope and move forward- -.

Hope it helps

Thank you  :)
