Preparation

Training & Preparation

There is no fixed syllabus to memorize. The best preparation is practicing each of the six domains and getting comfortable reasoning under time pressure.

Where to start

Build reasoning skill, not memorized facts

GRC problems draw on general reasoning ability rather than a curriculum, so the most effective preparation looks different from studying for a normal exam.

Work through past problems

Past Qualification, Semi-Final, and Final Round problem sets and solutions are published on this page a few weeks after each edition concludes. Working through them under timed conditions is the single best way to calibrate your pace.

Practice each domain

Rotate deliberately through deductive, probabilistic, causal, and strategic reasoning, critical reading, and modeling & estimation, rather than only practicing the type you already find easiest.

Read outside class

Short pieces on statistics, argument structure, and decision-making translate directly into stronger critical reading and modeling performance. Ask your teacher about the Semi-Final's research-paper component in advance.

By round

What to focus on

Before the Qualification Round

Skim all six domains so nothing on the problem sheet is unfamiliar. Since collaboration is allowed here, working through the five problems with classmates is a good, low-pressure way to compare reasoning approaches.

Before the Semi-Final Round

Practice reading a technical paper quickly and pulling out its core claim and evidence — that skill carries directly into the research problem. Arrange your supervision (teacher or online system) well before the registration deadline.

Before the Final Round

Time yourself on mixed problem sets covering every domain from earlier rounds; the Final Round rewards speed and breadth over depth on any single topic.

Sample problem

Try a Knights & Knaves puzzle

A classic deductive-reasoning warm-up in the style of the Qualification Round. Knights always tell the truth; knaves always lie.

The puzzle

You meet two islanders, A and B. Each is either a knight (always truthful) or a knave (always lying). A says: “B is a knave.” B says: “A and I are the same type.” What is each islander?

Work through the two possible cases for A, then check which case makes both statements consistent with the knight/knave rule.

Worked solution

Case 1: A is a knight. Then A's statement is true, so B is a knave. A knave's statement must be false, but B said “A and I are the same type” — since A is a knight and B is a knave, that statement is false, which is consistent with B lying. This case holds.

Case 2: A is a knave. Then A's statement is false, so B is actually a knight. But a knight must tell the truth, and B said they were the same type as A — false, since A is a knave. Contradiction, so this case fails. Answer: A is a knight, B is a knave.

Problems like this one appear across all six domains at increasing difficulty — see the Resources page for downloadable practice sets and full past-round archives.
