Well before you even think about going Freelance you got to weigh up the risks and think about if you can do it. Going Freelance you will have the risk of times with no work, no income, clients you cant handle etc. If you’re working for a design studio you probably won’t have to deal with any of that.
With doing freelance work as well as being a good designer you’re also going to have to have good project management skills, business skills and communication skills to succeed. You will have to sort out getting the clients, writing contracts, creating schedules, managing the project, managing the business, managing finances etc.
You should also consider that while your business is taking off you will have to have enough money to sustain your living costs etc whilst your income is low.
This industry is extremely saturated with freelances, design studio etc. Today everyone thinks they can be a designer and make it by themselves, if you think you can do it then good for you but a lot of people fail.
I’m in my second year of uni myself and in the same situation, I've been thinking about it for a while now. I've just managed to get myself an internship for a year which will look great on my CV and I'm on an great wage so I'll get some savings. Then once I graduate I'll try and work for a design studio, I wont go freelance until I've had years of experience.
