ASTB-E common mistakes

ASTB-E · Understand the traps and how to avoid them.

Mistake 1

On a multi-step word problem, starts doing arithmetic before writing the equation, then runs out of time and guesses.

The MST is timed and adaptive, so candidates try to save time by calculating immediately; without a setup they lose track of intermediate values and rework the problem.

What to do instead

Spend the first 10–15 seconds defining variables and writing one equation; estimate the answer before computing, then eliminate choices that are off by an order of magnitude.

Mistake 2

Leaves mixed units in place-for example, divides miles by minutes or mixes inches and feet-and picks an answer with the right number but wrong units.

Under time pressure, candidates focus on the numbers and treat units as labels; rate and geometry problems often intentionally use mixed units.

What to do instead

Convert all quantities to a single unit system before calculating and carry units through the equation; check that the final units match what the question asks.

Mistake 3

Chooses a reading-comprehension answer because it is true in real life or sounds like expert opinion, even though the passage does not state or imply it.

The passages are often on familiar topics, so prior knowledge feels like evidence; the test rewards text-based inference.

What to do instead

For every option, point to the sentence or paragraph that supports it; eliminate any choice that requires outside knowledge, even if it is factually correct.

Mistake 4

Estimates mechanical advantage from how strong the pulley or gear system looks rather than counting supporting rope segments or gear teeth.

Diagrams invite visual intuition; candidates confuse a change in direction with a change in force, or assume more pulleys always means more mechanical advantage.

What to do instead

Count only the rope segments supporting the movable load or compute teeth ratios; ignore fixed pulleys that only redirect force, and write MA = load/effort before choosing.

Mistake 5

Reports a left bank when the aircraft is banking right, because the candidate reads the tilted horizon from the viewer's left/right rather than from the pilot's seat.

The horizon line tilts opposite to the aircraft's wing; without mentally occupying the cockpit, left-right is easily reversed.

What to do instead

Imagine sitting in the cockpit: identify which wing tip is lower relative to the horizon; if the left wing is down, the aircraft is in a left bank.

Mistake 6

Mixes up aircraft control surfaces and axes-for example, says the rudder controls roll or the ailerons control yaw.

Candidates memorize the three surfaces as a list without linking each to the aircraft motion it produces.

What to do instead

Associate each surface with a motion: ailerons roll, elevator pitches, rudder yaws; rehearse with 'aileron-roll, elevator-pitch, rudder-yaw'.

Mistake 7

Chases the UAV target with large, late stick movements, causing the cursor to oscillate around the target.

The tracking task rewards anticipation, but candidates react to the target's current position and overcorrect when they see error.

What to do instead

Use small, continuous inputs and lead the target slightly; practice smooth tracking with a joystick and focus on reducing error gradually rather than making one big correction.

Mistake 8

When the tracking task becomes demanding, stops monitoring the designated ear in the dichotic listening task and misses auditory prompts.

Divided attention narrows under load; the visual task feels more urgent, so the auditory channel is dropped.

What to do instead

Practice a fixed scanning rhythm-track visually while silently repeating the target ear's cues-and do not let one task monopolize attention; rehearse dual-task sets.

Mistake 9

Answers biographical items to project an idealized perfect-officer image, producing inconsistent or implausible response patterns across similar questions.

Candidates treat the inventory as a test with correct answers and try to infer what the Navy wants; inconsistency and social desirability can hurt.

What to do instead

Answer honestly and consistently, using the same standard across repeated or related items; do not try to guess the scoring key.

Mistake 10

Endorses every positive officer trait at the extreme end of the scale and never uses the middle or less desirable side.

Candidates think strong agreement on all desirable traits looks best, but uniform extremes can signal an unrealistic or gaming response pattern.

What to do instead

Use the full scale and rate each trait relative to your actual behavior; distinguish genuinely strong traits from ones you are average or weak on.
