You also might check to see if another school nearby would let you sit in on their test date. My son was an online student and since he was technically open-enrolled, our district would not let him take the PSAT there so I contacted a school in a nearby district and they allowed him to take it at that high school with accommodations for his disability. It was very nice of them. Covid-19 might change how welcoming other schools might be, but it could be worth a try.
