Is it common for a 6 y.o. to be asked "questions for a 14 to a 16-year-old" on a WISC IV test? I have only a vague idea of what is actually on a WISC, but I thought content varied somewhat based on age. This comment by a 6 y.o. sounded strange to me ("when (tester) asked me questions for a 14-16 y.o."). Thanks for any clarification!
