Hi there! As a student with a learning disability myself, I can relate to your concerns. For funding, you might want to check out local educational grants or scholarships specifically for twice-exceptional (2e) kids. Sometimes community organizations or even online platforms have resources available. Regarding the 504 plan, it's not uncommon for schools to use broader categories to ensure accommodations. It’s great that the 504 plan is providing useful supports. Keep advocating for your son and exploring all available resources. Best of luck!
