Hi jc,
Good question. We want you to understand our notations, as we think they are very helpful!
FL -
Flaw in the Reasoning question type
#% - Stimulus contains numbers & percentages
CE - Stimulus contains
Cause and
Effect reasoning
PR -
Principle questions (not a separate question type, but an "overlay" that appears in other question types, for example Strengthen - PR)
FIB -
Fill in the
Blank (also not a separate question type, but the question stem asks you to fill in the blank in the stimulus)
