What type of work can a student who is schooling

I will advice, you have a service rendering job at hand that you can practice when you are less busy. Such as tailoring, electrician, selling and buy, online part-time job etc. E.g when I was at an undergraduate. When am broke , I always turn my self to an electrician to do generator connection for student and repair electrical wiring problem to have some money. Which helped a lot. Also, I engaged in garden farming around my hostel to succour my feeding and many more.  So wise up.
