@romanigypsyeyes “useless” really? Look at the Iowa Test results you received every year ([url = http://idahoansforlocaleducation.com/wp-content/uploads/2015/02/sample-score-report-iowa-performance-profile-.pdf]here’s a sample). For language arts alone, you have 21 sub-scores grouped in 6 categories. I’d imagine that with 8-10 years of results like that you’d have a good picture of where you stand in the subject before junior year in high school. It’s way better than the 1-letter results for us (like A, B, C, D, or F).
If you can dig out your years of Iowa scores, maybe you can see patterns of the 21 numbers over the years and their link to your SAT/GRE language scores.
