Balancing work-school: getting a degree

Ok, so as the title says.

I want to finish school. Get my degree. I have 21 units left. So basically kung ifufulltime kaya ng 1 sem. Pero hindi pwede. Not an option for me na mag fulltime ako. I need to work.

Plan ko this school year pumasok ulit.

Any advice, tips on how to do this?

Thanks.
