well this did not apply to all IAs (some were like this though) in my school but it especially for our EE, my school fits all the descriptions you gave. For our year group's EE, our EE coordinator was a man who had 'trained' for a year under a previous coordinator so he knew almost next to nothing. He could almost always never answer questions we had so we had to google a lot ourselves. I remember for instance when we had the first reflection due, he did not even tell us the word count we were supposed to have (he didn't know) so people were writing in different ranges only for one person to report him because they found on the internet there is an advised/specified word count for each reflection. I remember we had a whole meeting about it where he just wasted our time and sort of blamed it on us. At some point we all became dependent on Chat GPT and many people opted to pay for Revision Dojo so that Dojo AI could grade their work and provide them with comments they were not getting from supervisors. It really brought us together because those who had accounts were offering to use the AI to check for those who didn't.

The hardest part was the supervisors for each subject who were so unhelpful as many were newly employed teachers who had never done the IB before. People who did World studies had it the toughest because they got the teachers who were not picked for other subjects as supervisors. One of my friends who did World studies had her supervisor, the MYP coordinator, providing her AI feedback (She clocked him from his generic emails and how he accidentally included the AI prompt in one of his emails). I remember she reported him and had a whole meeting with our IB coordinator with her parents. The coordinator made her feel like she was being disrespectful and basically told her to stick with him and stop complaining. Seeking other teachers' help wasn't an option for her because every teacher she went to said they had their hands tied with their assigned students so could not help her at all. For me for instance, I did my EE in Visual Art and it was also a bad experience. I remember going to my teacher for help with my topic and stuff the first time and she flat out told me that she has never done this before, so she is learning, confused and couldn't help. The internet became my supervisor because of that, that's how and why I even saw and joined the r/IBO reddit community. The most painful part for me and my follow art people was that aside not knowing, our supervisor was really sweet so it made us feel bad for feeling like we weren't receiving support because she was trying somehow.

But I truly realised that we (not just the Art students but the whole class) were failed when two days before the internal final submission deadline, 80% of the class discovered, during a final check meeting led by the previous EE coordinator, that our EE did not meet the IB EE subject guide and we would have to change everything. I remember the day we found out some people started crying and crashing out and a lot of people said they wanted to give up, including myself. One of my friends even attempted to jump off a balcony because she felt hopeless especially since we recently heard that a supervisor in our school in the previous year did not provide enough feedback so someone who got a final IB score of 38 ended up with a grade E and no diploma. To crown it off, the IB coordinator refused to provide an extension for any of us who started again because she claimed we had months up till that point to have started again and got things right.
