I think it is more reasonable to study while working. First of all, for the family conditions are not very good, you can study while you are employed, or take the postgraduate entrance examination. It's good to be a junior college student. In order to learn various skills. It is also good to attend various training courses. This will be more efficient and reduce costs, as long as everything is feasible. Studying while working, these two things are not contradictory, if they are separated. Use your spare time to study and improve your skills. This is definitely a good thing, allowing you to give full play to your strengths.
