18 year old, pretty good in English, can I work online? [More in desc]

So, English is not my first language, but I have a international certificate of it that I completed an "intermediate language exam"

I want to leave my crap school, because I am starting university from September, but if I leave my school, I will be no longer a student by the law, and I can't do "student jobs". (Student jobs here means that the firm that finds a job for me, and they + the employer can pay less tax etc etc... they like to use students, that's it in a nutshell)

On the other side, I live in a small town, and there aren't any jobs where I can work at without being a student, until I start the university in September.

So what I am doing now is I go to school to have a warm place for 6 hours literally doing nothing, or not going in at all...

SO AFTER YOU READ MY STORY:

I need to find an online job, be it anything, so I can give money to my family and not just fuck around doing nothing and spending their money.

I would like to hear all of your opinions. Thank you!

TL;DR = In the need of an (or more) online job, because I am in a bad situation.
