You can explore "Sample Items" on the OECD PIAAC website, which show how you might interact with digital texts or numerical charts. While you won't get an "A+" or "F" grade immediately, the survey provides a fascinating look at where you sit on a 500-point scale. However, the primary focus of PIAAC is the "International Results" report, which compares the skill levels of different countries to help improve adult education policies.
