Social Work student driving license

I am currently a third year Social Work student at the University of Stellenbosch. I will be graduating next year and to get a job as a social worker one needs to have a drivers license. I have been having lessons on and off with the money that I can afford but it becomes difficult when I have to choose between buying food and taking a drivers lesson. One driving lesson is extremely expensive for a student to afford. Therefore, any help will be hugely appreciated as living as a student is extremely expensive and achieving this goal of getting my drivers license is extremely important to my future.
