Hi Aarav sheikh,
You got a very good percentage and with this percentage, you can get into many top colleges in India under pmsss. Getting a low-ranked college is due to the wrong way of filling choices and not aware of good colleges. We will soon add lists of the best colleges in each region.
Now you got a college which is not good according to you, the possible solution we can suggest you is that , if you have the option to float the seat you can ad move to further rounds of counselling, otherwise you can drop the year as per your wish and work hard to get into a top-ranked college because a good college can open many opportunities for you.
Hope it helps.
