This sounds a lot like a hardware problem with a circuit that’s broken for that key column. Unfortunately, I don’t know how to help you fix the issue from the hardware side and from the information I gathered I don’t think you’ll be able to fix any hardware issues before your ACT. However, MateoConLechuga may have away to fix it through software * Press [prgm] (If that button doesn’t work leave a reply and I’ll describe how to do it another way) * Scroll to the right over to ‘NEW’ and press [enter] * Type in the letter A and press [enter] again * Press [2nd]> and scroll down to '''Asm84CEPrgm''' (If this is crossed out in blue, leave a reply and I’ll describe how to do it another way) * Press [enter] * Now type in EXACTLY the following characters (they should be on the same line as the '''Asm84CEPrgm''' token) * '''210100F53678C9''' * Press [2nd]>[mode] * Press [2nd]> and scroll down to '''Asm(''' and press [enter] * Press [prgm] * Press [enter] on program A * Your screen should look like '''Asm(prgmA''' * Press [enter] * If it just says ‘Done’ then it should have worked. Try the buttons again and let me know if they work again! Since your calculator may not be reliable, I think your best bet is to see if your ACT proctor has a spare calculator or if some student brought along a spare. If there’s no spares, then just know that most commands and operations you need are available in the catalogue (which you access by pressing [2nd]>).
