Original Logical Reasoning practice

One correct answer does not mean you own the skill. Work it again with a different argument, a different subject, and a wrong answer that is harder to dismiss.

It isn’t designed to flatter you. It’s designed to train you.

Train with a purpose

Make the weak point
your next assignment.

Choose the question family giving you trouble. Start at a difficulty you can learn from. Work upward as your explanations become more precise.

Targeted repetition

Practice the specific skill.

Work on conclusions, assumptions, flaws, inferences, strengthening, weakening, and other Logical Reasoning tasks without waiting for them to appear in a full test.

Progressive difficulty

Keep raising the demand.

Move from foundational work to demanding arguments and close answer choices. The aim is reasoning that holds up when the wording gets less forgiving.

Original material

Meet an unfamiliar argument.

Fresh questions give you a chance to work through the reasoning without remembering an answer from an earlier practice session.

After the answer

Name the mistake.
Then work on it.

“Careless” tells you very little. Did you reverse a conditional? Treat “some” as “most”? Choose a premise when the question asked for the conclusion?

Use the answer explanations to check your reasoning, then return to that question family. The useful result of a practice set is knowing what to do differently on the next one.

Original materials were developed using proprietary techniques.
