As Kaitlin has been progressing well in her test prep work, we today studied two more difficult data and logic questions. The first data analysis required an understanding of correlation and inverse correlation; the second problem required drawing inferences from conflicting psychological theories. We worked on parsing the second passage by noting the claim followed by the word"but" thereby suggesting that the passage will contradict the original thesis. We then completed going over Module 1 of Practice Test 2 which focused on grammar. I provided additional instruction on the SAT's idiosyncratic use of the colon.
