In some cases being in the school physically is advantageous because, you'll meet professionals.
Sometimes a professional is hired to teach and they often come from companies you and your colleagues will be eyeing.
The difference really is making connections which makes it easier to get your foot in the door. Surely you've been told "It's who you know"
Some places really do expand themselves by cherry picking fresh graduates, for they are cheaper than someone whose been in the field for decades, while the experienced worker still gets the job. This is why they cherry pick though.
If on the other hand, the school doesn't offer instructors that are currently working in the field, then there is no real benefit to driving yourself into student debt.
My personal experience with college was very good. I totally wasn't learning that stuff on my own, and we all helped one another understand things about a software no human being in their right mind knows how to use 100% Still though, there are guys that learned it on thrir own in their garage and scored a career. ( In Canada an employer can hire anyone they want, regardless of their level of education. Not when it comes to doctors and serious shit though )
Go to the school and request a tour. You will see students there, talk to them when you get a chance. They will be prideful in what they are making themselves out to be, do not envy them, and find out if their instructors are professors or professionals. If they don't even mention that, then they are most likely professors, because a school with multiple professionals as instructors is a major selling point.
Finally, when you're going to meet people in your field. Please DO NOT, bring deloris the explois, you will lose your shit and end up in a cell for manslaughter.
