In order to take your online test, it is strongly recommended that you arrange to visit a Marlins Approved Test Centre in person. This is required by many companies, flag states and oil companies to ensure that you take your test at the premises of an Approved Test Centre, under supervised exam conditions. For details on your nearest Marlins Approved Test Centre, please visit: http://www.marlins.co.uk/approved-test-centres/ It is possible to take your test privately online or at a location which is not a Marlins Approved Test Centre, by visiting www.marlinstests.com, but please note that you will receive a different "standard" test certificate format that may not be accepted by some employers and flag states. We would advise that you speak to your employer/recruiter to check what is required.
