Possibility versus Certainty
Distinguish a conclusion that could be true from one the passage establishes.
How to prepare for the CSVT
Use 601 original passage-and-statement questions to locate relevant wording, preserve scope and qualifiers, distinguish support from contradiction, and stop assumptions filling evidence gaps.
Core concepts
Concept 1
possibility
Exam cue: Ask whether another outcome remains consistent with the passage.
Concept 2
probability
Exam cue: Match may, likely and will to their stated strength.
Concept 3
certainty
Concept 4
alternative explanation
Risk pitfalls and guardrails
Promoting may to will.
Guardrail: Do not copy official questions, invent a fixed test length or weighting, replace passage evidence with outside knowledge, treat unsupported as False, infer score from difficulty or rely on returning to an earlier item.
Treating the most likely explanation as the only explanation.

Memory anchors
Could is not did
Possibility does not establish occurrence.
Likely is not certain
Probability leaves alternatives.
Alternative test
A passage-consistent alternative blocks a necessary conclusion.
Match modal strength
May, should and must are not interchangeable.
Confidence follows evidence
Do not strengthen beyond the wording.
Checkpoint rule
Do the check-up only after you can summarize each concept in one sentence and identify one dangerous pitfall from memory.
