Need money for University

Hello everyone,

This is my 3rd time trying to post in this community and my last try,I am posting this again beacuse last post was not approved by terms of this subreddit.

I am 21y old student from Serbia,studying at Faculty of Transport and Traffic Engineering and i am also working full time in petroleum products storage facility.

This is my 3rd year at this University and for the first time i do not have enough money to pay my first payment which is 400€ (40% of the whole year payment which is 120 000rsd=1000€).

In my first year i was on Republic Budget so i was paying 100€ for the whole year, but to keep that budget i need to complete 10/12 exams per year which i didnt do because i work full time to support my family.

This year i will be able to make enough money for university because i need to pay 300€ every fourth month but i dont have enough for my first payment which is 400€ -1st October (Last Day).

I tried to ask some friends for money but they also have their struggles so I became desperate and decided to ask here
I also put my Play Station 3 and 4 for sale but no one wants them so i dont know what to do…

If there is someone who wants to help i will give all my information,bills,and show everything you need to make sure you know that you are really helping me with this…

Thanks in advance <3
