IEP's and 504 accommodations are legally binding. Schools that don't enforce them are open to lawsuits. You need to continue with your accommodations because when you head to college those same accommodations can be followed through on the college level. You can receive accommodations on standardized tests such as ACT and SAT. No need to be embarrassed about these accommodations. They are what you need to help you have success in school. Insist that your current accommodations are followed. You have a legal right to them.
