EdReady never tells you which questions you got right or wrong. There is a progress indicator that tells you how far along you are in the test, based on how you're doing. It may not progress evenly, because different questions can be worth different amounts. But the progress bar is not telling you if you go the answer to a question right or wrong.
If you get to the end of an assessment, and you did not "master" the topic, that does not indicate that you missed any particular question. It means you did not achieve the "target score" set by your school.
It is best to go back to the study materials and continue to learn, then retake the test again. Pay special attention to the Topic Text, as it is the most comprehensive study material provided in EdReady, and it covers all of the material you will be tested on.
