Postal Examination 914 - The Exam for Electronics Technician

Examination 914

Examination 914 is the exam for electronics technicians. The test is broken down into two parts: Part I: deals with basic mechanics, basic electricity, and basic electronics; Part II deals with mathematical computations and how to follow instructions. (For this exam see Strategies for Standardized Test, multiple choice and vocabulary tests and solving mathematics problems on pages 253-257 in The Book of U.S. Postal Exams & Post Office Jobs:How to Be a Top Scorer on 473/473-C/460 Tests & Other Postal Exams to Get a Post Office Jobs by Veltisezar B. Bautista.)

For the reading comprehension part of the test (Part II), see Reading comprehension, pages 177-180 of the same book.

(For a complete sample test, see The Book of U.S. Postal Exams.)

Here’s a part of the exam:

Author's Note: See Strategies for Standardized Tests, multiple-choice test techniques, pages 253-257, and review any books about basic mechanics, basic electricity, and basic electronics.
