Engineering Ranking

See, if your JEE score is below 70, then there is very less chance for you to score good marks in the next year. (I am talking about the chances, there can be exceptions but exceptions are very less)
Still, if you know that you won't get any decent college this time and have a decent grasp over the basics, then go for dropping.
