Firstly, congratulations upon this small but significant milestone that you have achieved! Secondly, I’m glad that you are actually open to new suggestions and changes. Alright, so here are some things that you could do :-
1) Join a club or a chapter or an NGO. It will keep you busy, active, hone your networking skills and give you a nice circle of people to interact with. Also, most companies while recruiting take a look at the extra curricular activities that you have done in college and do not get impressed by a flashy cgpa alone.
2) READ. Read novels, blogs written on topics of your interest and newspapers. Enrich your mind with knowledge, vocabulary, creativity and imagination. It’s a very good way to develop your personality and give it varying dimensions.
3) Socialize. Personally I feel college life is meant to be the best years of your life where you can make the best of friends and meet a lot of people from different backgrounds. So throw yourself out there (not literally Ofcourse :p) and make lots of friends and try meeting as many people as you can. Not only will it help you in the future, it will also help you in staying in the loop regarding any matter, it will teach you a lot about different cultures and once you master the art of conversing, people will love to be around you
