Key examiner messages
Top priorities from the principal examiner before you revise
TGAT2 Critical and Logical Thinking measures reasoning under time pressure through 80 items in 60 minutes: verbal reasoning, numerical reasoning, spatial reasoning, and logical reasoning, each with 20 items.
Official blueprint: Verbal 20, Numerical 20, Spatial 20, and Logical 20 items, 80 items total in 60 minutes.
TGAT/TPAT score conversion uses Ti = 50 + 8.69031 * (raw - mean) / SD.
The blueprint gives equal item weight to the four reasoning domains, so preparation should not over-focus on numerical reasoning alone.

Deep insights
What top candidates did
Techniques and approaches examiners rewarded in this series
1. Use a 45-second rule
Eighty items in sixty minutes means the paper is a triage test. If the first method is not visible within 45 seconds, mark the item and return after completing easier reasoning sets.
2. Translate conditionals into symbols
Write A -> B, not A, not B, all, some, and none in the margin. Validity becomes easier to test when language is converted into structure.
3. Estimate before calculating
For numerical items, approximate the answer first. Estimation removes many distractors and prevents percentage-point and percentage-change errors.
4. Mark orientation in spatial items
Put a dot, arrow, or labelled corner on figures before rotating or folding. This separates true rotations from mirror-image traps.
5. Separate argument from opinion
For verbal reasoning, identify conclusion, evidence, and assumption. Attractive value statements are not correct unless they follow from the evidence.
6. Practise mixed sets
Do not revise by topic only. TGAT2 fatigue comes from switching between words, numbers, shapes, and logic, so practise full mixed blocks.

What examiners measure
1. Analyse verbal arguments, assumptions, conclusions, and implications. 2. Interpret numerical information from tables, charts, ratios, percentages, and sequences. 3. Manipulate visual, spatial, and diagrammatic information accurately. 4. Apply formal logic, conditional reasoning, classification, and pattern rules. 5. Choose valid conclusions while resisting plausible but unsupported distractors.

Examiner notes & key calculations
- Official blueprint: Verbal 20, Numerical 20, Spatial 20, and Logical 20 items, 80 items total in 60 minutes.
- TGAT/TPAT score conversion uses Ti = 50 + 8.69031 * (raw - mean) / SD.
- The blueprint gives equal item weight to the four reasoning domains, so preparation should not over-focus on numerical reasoning alone.
- The paper is designed for discrimination through speed and accuracy, not long written calculations.
- No negative marking means strategic guessing after elimination is preferable to blank responses.
- Spatial and logical items often have the highest time cost; skipping and returning is an intended exam skill.
- Numerical reasoning may be solved with arithmetic and estimation; advanced mathematics is not the point of the paper.
