What do you think about working while studying?

I`m a student now and I don`t know what to do with my incomes.In fact there are no incomes in my pocket :D.But I want to do something in this way.I need money to buy a car because it`s cheaper to drive my own car than using the bus.But I have no savings.I don`t have time for work because this means to cut the time for reading and learning.I`m thinking about student credit to cover my expense but I`m not sure.What do you think is this a good idea?I`ll be grateful if someone give me advice how to earn 200-300$/month.
