Good Luck!

The main question lies here is what is considered a good college because you knows who will qualify JEE main will be more than two lakhs students know the top two lakhs students will get the top in different colleges of India and if you have only want to get a seat based on JEE main rank then it is sure that those get a better rank will first get the seat in better colleges if you consider colleges after 2lakh students as good then yes. It is just a state of mind that whether you are in good college or not as you need to first to decide what college you would you consider a good college
