b. school grades are notoriously poor measures of school achievement; sean's iq scores are better indicators of what he has learned at school.

c. sean must have been feeling poorly both times that he took the test, because iq scores are generally very accurate predictors of children's school grades.

Explanation:

Grading in the school process is a method used to assess and categorize student achievement .

The classification of the IQ is the practice of classifying the score obtained in IQ tests with categorical labels, however it is proven that it is not the only thing that determines the success of a person. The intellectual quotient is an estimator of the general intelligence resulting from some of the standardized tests designed for this purpose. It is considered that the human brain is complex enough to not be able to measure intelligence with a single factor. The standard IQ test measures how smart a person is, traditionally, based on math or language. All other areas in which a person can excel or have natural capacity are not taken into consideration.
