The university won't help you in getting any scholarships. You are on your own in that case. You have to constantly check for these opportunities and grab them as soon as they appear. But keep in mind that to get an internship from colleges other than IITs, NITs, you have to show that you are better. Hence keep enhancing your skills and also don't let your CGPA go down as getting good marks here isn't quite difficult.
