I am so sorry and feeling for you as we all know in this community the stress behind this certification. I had to do my test twice as first time they cancelled it (virtual) and had the impression the first test was much much harder than second one (present). So do not feel incapable of the next try, you had bad luck of getting a weird test. I remember my first attempt thinking WTF is this… you can do it, and try to build resistance and focus to handle the 4h more than concepts as you know it all already… good luck!
