Instead of doing part-time and internships , I would suggest it's better to research and send your research to your University . They can cancel your fee and pay your bill according to your research . And then if you have hobbies like cooking etc . Then start a small level business ,even you if you're giving tuition then don't give it to primary students . Give lessons to high schoolers and if you're a PG student apply for guest lectureship in UG department . In this way you will not have any obstacle in your studies .
