The 567-item psychological questionnaire is long. Keep your concentration and be consistent in your answers.

The Terman-Merrill measures general IQ. Practise numerical series, verbal analogies, and spatial reasoning.

The Cleaver (DISC) has no right answers. Respond honestly according to your natural profile.

The physical test is eliminatory. Train 6 months ahead. Push-ups, sit-ups, and running are the main exercises.

The academic exam requires high-school (preparatoria) knowledge. Review mathematics and natural sciences.
