I think you validly think what you do. Your lens, however, is broken.
Let’s give your story 3 lenses. You can tell me if you see how different each is.
Johnathan “I can’t get any respect and people are always rude to me. I listen to authority but everyone is always trying to get me down. Nobody wants to help me and I have to fight for everything, only to be faced with petty people. I tried to get help from a professor once and I got a verbal smackdown for a minor mistake that everyone does anyway. Then when I tried to ask questions the rest of the semester the professor just ignored me and if he did answer he did so mockingly and told me to look at my textbook.”
Anna “I work really hard. I do all the readings that are required, I know the rules of the class and lab. I pay attention and I can’t stand all the students who don’t do the bare minimum taking up time asking questions that can be answered by doing what they are supposed to. I’m not paying to read the textbook! I could do that on my own. Even answering one of these questions the Professor takes up my valuable time.”
Professor “I have no idea what more I can do. I post signs everywhere, I have it in the syllabus, I tell the students frequently not to bring liquids or containers in. I get ignored and then when I enforce the rules that keep them safe, they get pissy. Just the other day a student came in and when I told him to put his drink away rather than doing that he stormed off and did not return. I’ve given up calling on him because he always asks things easily answered by reading what I tell him”
As far as advisors—I spent way more than my allotted 40 hours with students and many of my colleagues did the same. What we didn’t have time for were the students who came in at 4:45 on Friday before a break/long weekend who demanded to know how a massive degree change involving checking with other departments would go.
Universities are actually made up of smaller divisions called “colleges” and then even smaller divisions called “schools”. For instance, a common break down is University XYZ. College of Science & Tech. College of Education & Math. College of Arts. College of Business And a further break down the college of, say, Science and tech you will have the school of Tech — CS, IT, engineering, etc. School of science-- psychology, physics, biology. And that doesn’t even cover Masters, PhD and the like!
An advisor will only work under one “college” and typically with one school or two. In some larger schools, they may only work on one program. It’s not as easy as typing a code into the computer and printing out a new course of study. It’s a shame if you were never given a proper advisor, but my guess is that you were simply told to go to that department or to come back at a different time, or call during a break when the advisor would have the time (which a drastic change may take hours) to ensure you got the right plan in place.
“Laying out a pre-med pathway” is no where near as simple as you make it, especally with such a disaprate degree.
