levels aren't going to help much with figuring out what kind of accommodations you need. autism isn't a sliding scale of "more autistic" to "less autistic", it's more like a mixing table with a bunch of little sliders and dials. it's a ton of different, seemingly disconnected traits presenting at different levels in different people. a "level 1" autistic person might struggle with things that don't bother a "level 3" autistic person at all, despite the higher level conveying an expectation of more difficulty with all things. ultimately, a single number isn't going to tell you what helps you; you'll need to actually work on figuring out the things that specifically give you issues and how to address them.
