Hello ojhal singh

This is not only your problem but this is the problem of many students in every year ..

If you had 6 subjects in your 12 ,and you passed by calculating top5 subjects.. And you get rt in biology again

So, you havetwo choices

First is, You have to give that compartment exam again, A student have 3 chance to clear its compartment..

And second is,  you have to do the coarse which doesn't include biology as the main subject because you don't have any other option instead of these two

Their are many college in which you get admission on the basis of your 12 passed marksheet but you will not appear any govt enterance exam because biology is main subject and you have compartment in biology..

You Will only get admissions in private colleges

Hope this information is beneficial for you
