The July PCAT tests are the first two computer based tests. No one knows if there is any difference between the preliminary and official scores. However, I guess they will be the same because I did some search and comparison between the scaled scores and the percentiles with the previous test scores. They are the same. For example, I got 429 SS and 90 Percentile on this test. When making comparison, I also got the same percentile 90% with 429 SS in the January and last October tests.
