Want to earn a side income

Hi I'm M20 currently a student of pharm D 3rd years I'm looking to earn side income I come from a well to do family my dad pays me 1.5k monthly but he takes care of all expenses like fees,petrol etc. For me those 1.5k is very less and my course is 6 years long till then I wouldn't have any source of income for myself P.s I asked my father to increase the allowance he said I take care of all your expenses those 1.5k is for me to learn money management. Is there anyway I can earn subtle income while studying our colleges do provide us internships in hospitals in 5th and those to are unpaid
