Knowing how to diagram conditional claims is essential for every scored section of the LSAT. In LSAT Logical Reasoning, you have to diagram conditional claims very often with Must Be True, Must Be False, Could Be True, Sufficient, Necessary, Flaw, Parallel, and Parallel Flaw question types. In LSAT Logic Games, you’ll make some very nasty mistakes by incorrectly diagraming conditional rules. Finally, in LSAT Reading Comprehension, main points can be conditional, and many other question types will also depend on your ability to diagram.
All diagramable questions have very tempting sucker choices. This is because diagraming mistakes are easy to predict. So, an incorrect anticipation will probably show up in your answer choices. This makes diagramable questions pretty difficult.
