Yes! There are ways to succeed in life depending on your skills. People from tier 1/tier 2 colleges do have an advantage over you as a lot of good companies come for placements,they would have more exposure to various organisations and so on. You are still young and the tables can turn in your favour anytime provided you work hard for it and develop your skillsets.
Be the jack of all trades, keep learning new things as often as possible. Never ever waste your vacation holidays. Apply for internships and do online courses which add value to your resume. Work on projects by your own. Don’t give it to some project center. Do as many projects as you can, because you should make your work speak for you. Yes, by the time you graduate from a tier 3 college you might not be provided with as many opportunities as people from other colleges but that doesn’t stop you from achieving greater heights. Personally I would suggest you to do the following:
During college:
Please maintain a good CGPA. Many people would say that it’s not very important, it’s just an eligibility criteria. There are people who missed their dream companies because they didn’t have 0.1 or 0.2 in their CGPA. Maintain atleast 70% throughout your academics. Not 69.99% but 70.00%.
