can we get good collage by scoring good result in boards examination

Yeah! Obviously you can get best colleges in your state with good boards results provided if they allow merit based admission. But this is not applicable for professional courses. In most of the professional courses one have to give an entrance which is mandatory. But having a good marks in boards (above 0%) makes you eligible for numerous scholarships which can support your higher studies. Also exams like CAT have points based on boards results. So having a good boards result is always advantageous for numerous cases.

I hope my answer helps. All the very best for your future endeavors!
