How to make money as a student

​

Hey, I am Computer science student on The Faculty of Electronic engineering in Serbia. I used to work hard phisical jobs, worked as a waiter and some other jobs(i worked quite a lot in my high school time), then came my 2nd grade on faculty. The first was also hard, but I didn't care that much as i do now on my 3rd year. I have no time to go to work, i have so much deadlines for projects on Faculty (thats a required part for almost every course I have this semester) so I tried doibg somethibg online. I didn't ask for much, i need 20 to 40eur weekly, sobl tried clickworker. Apparently, it is waste of time. Upwork seems quite impossible to start without spending some money (which i don't have rn). So, can you recommend something online, but not playing games cause I really dont have much time, particularly i'm spending 6, 7, 8 hours studying (weekends are not included in this, i have more time for weekends). Is there any platform that can help me?

P.S.

Sorry for my bad English.
