Starting in January 2014, API will no longer be accepting paper applications. You must enrol in API's new online portal for application submission. API has also changed the examination delivery method from paper-and-pencil to computer-based-testing (CBT).

Additionally, there will no longer be one global exam day, but a 10-day testing window. This means each applicant will have a choice of when or where they want to test within the given window. Tests will be available at any of the Prometric computer testing centres around the world.

We have designed API 510 Exam Helper for the busy industrial professional who have very limited time for regular practice. Through API 510 Exam Helper, you can appear more than 500 practice exams. And, you need not be in your office or at your home; this is a mobile app, you can practice anytime, anywhere. API 510 Exam Helper benefit inspectors by:

Paying doesn't do anything

Paid for the subscription and still don't have the full app. Sent email and no answer. Feels like the developers abandoned this app.
