Presidential Security Service Grade 7 Bodyguard Officer Exam common mistakes

Presidential Security Service Grade 7 Bodyguard Officer Exam · Understand the traps and how to avoid them.

Mistake 1

Affirming the consequent

A statement with the same words can appear equivalent even when its logical direction changes.

What to do instead

Write P implies Q and try a case where Q holds for another reason before inferring P.

Mistake 2

Confusing some with all

An existence claim is expanded into a universal claim without additional evidence.

What to do instead

Translate some as at least one and retain that scope through every inference.

Mistake 3

Calling association a proven cause

A shared trend can conceal selection effects, reverse direction or a common cause.

What to do instead

State the competing explanation and ask what design or evidence distinguishes it.

Mistake 4

Averaging rates without weights

Group sizes disappear when only the displayed percentages are compared.

What to do instead

Reconstruct successes and attempts, then divide combined successes by combined attempts.

Mistake 5

Confusing percent with percentage points

Both calculations use percentage symbols but different denominators.

What to do instead

Subtract rates for percentage points and divide the change by the original rate for relative growth.

Mistake 6

Using incompatible units

A plausible arithmetic answer can hide a minutes-to-seconds or squared-unit error.

What to do instead

Convert units before substitution and check the final dimension against the requested quantity.

Mistake 7

Accepting one satisfied rule as enough

A local fit is mistaken for a complete feasible arrangement.

What to do instead

Check each constraint against the entire proposed arrangement before marking it valid.

Mistake 8

Importing foreign agency rules

A related example is treated as an actual local statutory authority.

What to do instead

Use only the stipulated exercise rule and verify actual agency requirements separately.
