ICAS Science vs ICAS Mathematics
ICAS Science tests science understanding, interpretation and reasoning. Students need to read scientific information carefully, interpret data and apply concepts.
ICAS Mathematics tests mathematical problem solving, logic, pattern recognition and procedural fluency in unfamiliar contexts. A student can be strong in one and not the other, so use results diagnostically.
