First of all, I would like to explain my current education situation. I have moved a lot when young, and have been part of different educational system, when 10, I was in the UK for 2 years, when 13, in Brazil for one year, and from 13-19, I was in The Netherlands, and from 19-22 (current), I was back in Brazil.
Computers have always been my main interest, I started programming at a young age (12 years old), and when 15, I had my first backend developer's job, however, I was never a good student, I got kicked out from a few schools, had some low grades and etc. In The Netherlands, the school systems works a bit differently (for the dutch readers: I was doing MBO), which is a like a "low technical school". I wanted to go to the university and start studying what I really wanted: Computer Science and Computer Security. So I finished my MBO 3 (you can only go to a university after 3 years of MBO 4), so clearly I was not allowed to enter the university. Fair enough.
When I arrive in Brazil, I decided to give a go, and translate my Dutch education papers, and voila, I was allowed to officially start a Bachelor of Computer Science, and so I did.
It's been 2 years now that I am studying a private university. However, I would like to return back to Europe, due a few personal reasons (I am completely alone here, and the way my current university works is not how I like it, mostly because they don't really care about anything, and so do the students. There is no organisation, and it seems I am not involving much, professors don't seem to be able to answer most of your questions and etc).
However, every university I tried to apply back in Europe, they ask me for my high school degree, and of course I "don't have any!" because of the MBO I did in The Netherlands. So I decided to get a transfer, again, all the universities I tried asked me for my High School grades. I tried one in which accepted a "university transfer", so I sent them my university papers, and my MBO paper (hoping they would accept me), well, no, they sent me a letter saying "due to the school you did in The Netherlands, we are not allowed to accept you".
This is starting to make me very upset, so I am trying to make a decision weather I should drop out of university, return back to Europe and start doing some certification on the area I mostly like. Though I am not sure if this is a good idea. It saddens me because I really like to be part of a university (not the current though). Currently, my aim would be to follow as a independent security researcher.
How worth is dropping out of university? What should I be aware and what are the main steps I should follow to be a security researcher on my own?
Update If relevant, I have the following citizenship: German and Dutch.
