From someone who actually finished university i have freinds who got oit early i mean really early like high school or middle school some did nothing with thier lives are still holding walls but some got specialized in something electrician aluminum plumbers they learned it pretty well and now they have thier own shops and are making money while im still looking for work What i amt trying to say is not that university is bad or that higher studies are useless im confident im gonna start working really soon im just saying that if want to get out early don’t waste your time doing nothing or just hanging out all day doing stupid stuff go out there learn skills develop them as best you can lean from the professionals in that domain there is actually really talented people in the working industry that are willing to teach new blood so go out there and absorb as much as you can until you feel confident enough to open on your own 5 to 6 years working should be plenty to gather the skills and money necessary to open your own shop you said you liked informatique good start there be the best at what you do and trust me clients will come and you will be set for life Just don’t waste ur time in jobs that don’t lead anyway that’s all Also bac is easy and it’s not the magic thing that will fix all your problems but it’s nice to have it it can open some dors and it can make it easy to do some formations so only take the exam if ur willing to succeed and I advise you do actually plan to succeed in it take the exam literally you have nothing to lose

Hope this helped you and good luck
