I wish that I knew enough when my oldest was tested to ask about spoiled tests and optional tests. At the time, I just took her one majorly low PRI score at face value even though the tester told us that dd had "handed the blocks back" and stated that she could not do that section at all. I may be a bit off on the FSIQ, perhaps it is a tad higher, but it probably isn't the best estimation for him anyway given the variance in the scores.
