What this test measures
Correct and incorrect answers indicate knowledge of the concepts in this practice. They do not establish a trait profile, diagnosis or job fit.
- Find the subject before choosing a verb. A phrase between the subject and verb does not change whether the subject is singular or plural.
- Two complete sentences need a full stop, a semicolon, or a suitable conjunction. A comma alone usually creates a comma splice.
- Use the surrounding sentence to test a word's meaning. A familiar-sounding word can still be the wrong choice.
