Checking and Comparing: Careful-Copy and Counting Tasks

Four methods for checking tasks: compare character by character, check copies chunk by chunk, count matching pairs, and count only what meets the condition.

What it is

Checking and comparing items test how carefully you read. You compare two lists, pick the exact copy of a sentence, or count the words or digits that meet a stated condition. There is nothing to memorize: you need a method that stops your eyes from skipping small differences.

The review materials give no rules for this topic. Everything in this lesson is a method built from how the practice-test items are made and the traps they use.

Why it matters on the exam

These items are part of the Clerical section of the Sub-Professional test. Each one is quick and certain if you use a method, and easy to miss if you only glance.

At work, the same skill catches a wrong digit in an amount, a misspelled name on a certificate, or a missing line in a copied memo.

Rule 1 of 5Method: character-by-character comparison
Compare two strings one character at a time, from left to right, at the same position in both. Characters include letters, digits, spaces, signs and punctuation.
