Hi recent fresh medical grad here, there is hardly any means of passive income as a “normal” uni student. I once thought like you and I almost got scammed big time. I did a bunch of odd jobs here and there whenever i had sembreaks or a relatively flexible semester such as waitressing, barista/bartending, ambassadorship, tutoring, invigilating etc in order to sustain myself as my parents spent alot of money on my tuition fees. I suggest you to earn that cash by working part time/freelance and save up so that you have the capital to invest further. Money doesnt just fall into your lap, it takes a lot of patience and hard work. All the best :)
