    Talk it through

    The examiner asks, then follows up

    Answer out loud. The examiner listens, then pushes for detail with the next question, the way the real board does when it hears a gap.

§02The problem

Studying hard, still guessing

  1. P-01

    Generic study guides written for every certificate at once. Nothing tells you where an EOOW examiner will actually push.

    Generic
  2. P-02

    Notes scattered across three notebooks, a phone camera roll and half a dozen PDFs from other cadets.

    Scattered
  3. P-03

    You can recite the theory, but you freeze the moment the examiner asks "and then what happens?" for the third time.

§07FAQ

Straight answers

Q.01When does it launch?

When it's ready, not before. Waitlist members hear first and get in early.

Q.02What is the founding-member discount?

A launch price for waitlist members that's lower than the public price. The exact figure will be in your launch email.

Q.03Is it current with the MCA syllabus?

Yes, checked against the current MCA syllabus, last reviewed August 2026.

Q.04Does this replace official study material?

No. It's a supplement. Keep your official MCA guidance, textbooks and college notes — this is the layer that turns them into oral exam answers.

Q.05I'm not on an LNG carrier. Is it still relevant?

Yes. It was built from LNG carrier experience, but the content covers the general EOOW syllabus that applies across vessel types.

Re

The oral

I sat this exam not long ago, and the thing that got me through wasn't more reading. It was saying the answers out loud until they held up under pressure. That's all this is: the notes I made for myself, plus an examiner you can practise against at 0300 in your cabin. Good luck in the room.

§09About

Who's behind this

Alex, 4th Engineer, in the engine room.

Hi, I'm Alex. A lot of cadets have been asking me recently for revision notes or help studying for their oral exams, so after sending my flashcards and study notes to a few friends, I thought I'd compile it a bit nicer to try and help more people. I'm currently working as a 4th Engineer with BP on their LNG ships, as well as doing some volunteering on Logos Hope in my down time.

The content found here comes from my own notes, used to pass my EOOW oral exam in September 2024. The flashcards you'll see have the same content I used to have friends drill me on in the run-up to my exam, but I've polished them from the handwritten notes I used into this pack for you to download and use for your own exam.

I then decided to take it a step further and build an examiner you could talk to for a bit of practice, which, when I've shown it to colleagues at sea, they all agree is quite impressive.

I hope you enjoy what I've put together and find it very useful for your exam prep.

Good luck, and I look forward to hearing when you pass.
