People often believe standardized tests are IQ tests.  They aren’t.

You have to know what’s on the tests.  You have to know how to do what’s on them.  And, you have to be able to do your best on any given day.  All are knowledge and skills that you can develop — that’s what I help you do.  Along the way, we might even help you learn more about the ways you study, think and perform that can could be meaningful to you long after you have forgotten what your test scores were.
