API 510 OPTIONAL WORKBOOK
Module Objective:
The Inspector shall have a sound general knowledge of the entire API 510 Code (Section 9 and Annex E are
excluded as per BOK).
Note: As API is in the process of developing new question formats (AIT's), CKRC is also adding new questions &
question banks to our courses.
These additional Modules are entirely optional and still in the developmental stages - we encourage students
to challenge as many questions as they want/need. We have not included a reading assignment, but Module
2.1 is also based on the API 510 document and can be attempted as either Open or Closed book.
The Quiz is not timed and can be attempted multiple times.
Module Instructions
Module 2.1 is in a test format.
This is an opportunity to familiarize yourself with the Recommended Practice and to test your current
understanding and knowledge base.
There will be three sections to this module
Section 1
 Review module and identify the required reading assignments (RA).
 Thoroughly complete the RA (This may need to be read through several times depending on your
familiarity with the material).
 NB: It is highly discouraged that the test questions be reviewed prior to attempting the RA.
Section 2
A downloadable PDF document containing the questions to work with offline.
(The test will have the same questions that will be found within the quiz; however, the order of the responses
may differ).
 Attempt the module test paper as an open book attempt (Record all reference and calculations, if
applicable).
 NB. All references and calculations should be recorded for comparison with the references provided
during the online quiz. This will be essential in later discussions of any problem areas that the student
requires further clarification or assistance.
Section 3
An online quiz containing the questions for grading purposes. This is an open book test.
 Each quiz will require a passing mark of 95% to signify module completion.
 The score and references for all correct answers will be available once the quiz is submitted.
 If a score of less than 95% is obtained the student should repeat the questions that were marked as
incorrect.
 There is no limit to the number of attempts.
 If a score of ≥95% cannot be obtained and / or there is disagreement with any of the proposed answers,
references or calculations provided, the student should submit a request for assistance / clarification
to the course instructor.
NB. It is essential that test / quizzes be attempted by each individual, collaboration on tests and quizzes is highly
discouraged, and will defeat the intent of the preparation course and will only become evident in the final score
of the API ICP Examination.
