For paying school fees you need to work part time due to your classes and studies.you can do tutoring to the students of lower standards which is the most preferred job during studies in this you are learning while earning so its a win win situation for you.

Also,you can do freelancing whether it's writing, graphic design, or coding, and offer your services on platforms like Upwork or Fiverr or you can search job near you in shops as salesperson or any.it is quite challenging but once you are ready to face it you will definitely make you way.

ALL the best for your future endeavours!!!!
