GUIDE QUESTIONNAIRES
for seafarers
The Annual Publication of Database of Questionnaires is mandated in Republic Act
10635 or the Act Establishing the Maritime Industry Authority (MARINA) as the Single
Maritime Administration Responsible for the Implementation and Enforcement of
the 1978 International Convention on Standards of Training, Certification and
Watchkeeping for Seafarers, 1978, as amended and International Agreements or
Covenants related thereto and its Implementing Rules and Regulations.
These sample questions have been reviewed and validated by our respective Board
of Examiners which may serve as a guide for the review of aspiring Marine Deck and
Engineering Officers, towards the successful completion of the Theoretical
Examination.
The following sample questions do not reflect the actual set of database of questions
given during the theoretical examination. Examinees are encouraged to study the
contained sample questions and probable answers as they are intended to give an
indication of the format and difficulty level of the theoretical examination.
You may access these guide questionnaires with your smart gadgets anywhere and
anytime at your convenience. Please consider the environment before printing.
Thank you.
