Getting to a one year bachelors degree without CLEP

[Bosnian_Slovenian]

I live in Slovenia (the city doesn't matter, It's a small country)
Your Age: ... 14... I know, probably thinking about this a bit too early, I know, please don't judge.
What kind of degree do you want?: CS, EE or business would be preferred, any STEM degree would do
Current Regional Accredited Credits: No university credits of any kind.

Budget: Around 15k max, willing to grind at the local McDonald's.
Commitments: Would have to work on studying for the matura exams while gathering credits.
Dedicated time to study: I can wake up early (5am) and I have time during the weekend and the holidays. Currently have discipline issues, I need to fix that while still in middle school.
Timeline: 12 months
Tuition assistance/reimbursement: pretty much N/A

The reason I'm thinking about this right now is because I found a way to finish high school in one year, so I might as well figure out how to finish uni in one year too. I hope this is helpful!
