FWIW, our ds' WM score went up significantly from the time he was first tested in 2nd grade to when he was tested again prior to middle school - it's now up close to his VIQ/PRI (processing speed is still relatively low
That's what my oldest's profile looked like the one time she took the WISC (high VCI, PRI, and WMI and low-avg PSI). She, too, does not have ADD and she presents quite differently than her sister. Her very good memory has been extremely helpful to her in school and she's a kid who is easily recognized as gifted by teachers, schools, etc.
