Hello student,
You have not mentioned which state you belong to. With a score of 525 in obc category, you have chances of getting a seat in the government medical colleges when comparing the results of previous years. But it all depends on the state you live in. For example, with this score, you can get a seat for sure in Uttar Pradesh while it is not so in the case of states like Tamilnadu where the scores are really high. But one thing to keep in mind is that scores and ranks vary each year with toughness of the exam and availability of seats. However you can predict the colleges which you are likely to get using the given link
