Dear Hiren,
No without entrance exam you can't get admission in any good college coz now every reputed college accepts admission through entrance exam score.
there are private universities which accepts admission on the basis of their own entrance exam score.
good luck

Hi
You can start preparing for upsc even now as you need to know your subject from class 6 onwards. Just read the interview of this year topper who cleared it in the first attempt after her graduation. The point is to study consistently and persistently. Each one of us have their own learning style so you must know that to get the optimum benefit. Start with a sample paper to know your level and then work on understanding the concepts.
