What you’ll learn
What each unit actually teaches you to do
Open Awards is a National Awarding Organisation, Access Validating Agency and End-point Assessment Organisation specialising in the delivery of Functional Skills, Alternative Education and Vocational qualifications.
These are the units Open Awards registers against this qualification. It is a catalogue, not a syllabus. Which of them you take depends on the combination the qualification requires, and that is set by the awarding body rather than by us. Every unit here is regulated, and every one you earn is yours to keep.

The honest bit
You’ve started things before
Most courses were built for a room full of people who aren’t you. A cohort moves on whether or not your week allowed it, and by the third week the thing you’re behind on becomes the reason you stop opening it.
There’s no cohort here, and no timetable to fall behind. Before anything starts, Zavmo asks when you’re sharpest and how long you can realistically sit down for, then builds the sessions around those answers. A bad fortnight changes your pace. It doesn’t put you behind.
And you only pay once you start learning. Searching and planning are free, and you can cancel any time — so the cost of finding out is an afternoon, not a year.
Your passport
Every credit is a stamp you keep
Level 3 credits are regulated. They don’t vanish when a subscription ends or a website closes. They travel to any employer, and Zavmo keeps the map of what you’ve earned and what’s next.
Each stamp is a real unit registered against this qualification.
Who’d teach you this

The Evidence Evaluator
Assessor
Helps you show what you can actually do, gathering the evidence that proves it as you learn.
Meet all twelve tutorsWhere this connects
Where these credits take you
A qualification is never a dead end here. See the jobs its credits open, the national occupational standards its units map to, and the future skills they quietly build.
- Assisting in mooring and berthing operations
- Maintain a state of readiness to respond to emergencies
- Present offshore survey information
- Respond to Offshore Installation Emergencies
- Respond to emergencies on offshore helidecks
- Respond to emergency on location
- Review, process and interpret offshore survey data
- Travel safely by helicopter to an offshore installation
Skills it covers
What the job actually needs. These are the standards the units are built against, in the words employers and awarding bodies already use for the work itself.
How you’ll actually learn this
One-to-one, on your own real work
A qualification is usually something done to you: sit the class, sit the exam, hope it sticks. Here it’s the opposite. You learn it one-to-one with a companion, on your own real work, and you keep going until you can use it, not just recall it.
Applied to your own work
Learners will develop skills to use Mercator charts for navigation, including plotting positions and converting compass and true headings and bearings. The unit also covers establishing Dead Reckoning positions and calculating tidal heights and streams.

One to one, not one to many
No two people run this the same way
A course is written once and handed to everyone. This is assembled around you, and keeps changing as it learns you. Five things it reads, and what each one changes.
- Your actual work Every unit is taught against a live piece of your own work, not a worked example from a textbook.
- What you already know The first conversation finds your starting point, so you skip what you can already do and spend the time on what you cannot.
- The conditions you learn under Not a learning-styles quiz. The evidence does not support those. The dimensions the research does back, read once and used to shape the plan.
- How far you got last time It picks up mid-thought. The tutor knows what you said, what you struggled with, and what it asked you to try.
- Which tutor suits the moment Twelve of them, each for a different kind of thinking. The one who walks you through a first idea is not the one who stress-tests it.
See how you learn, free. Eight questions, no sign-up. A directional taster; the diagnostic inside Zavmo goes deeper and keeps adapting.
Why it sticks
Most courses stop at remembering
There’s a well-known ladder of how deeply you learn something, called Bloom’s Taxonomy. Most courses get you up the first two rungs: you remember some facts, you pass a test, you forget it. Real skill lives at the top. Judging, deciding, creating. And this isn’t a generic ladder: every rung has a named Zavmo tutor who walks you up it.

The value
Why the companion is worth £70 a month
You’re not paying for the units. They’re regulated, and the same wherever you earn them. You’re paying for the one thing that decides whether you actually get there: a companion that makes them stick, on your real work.
That is one-to-one on this qualification, every day, on the work you already do, for £70 a month. Your first module is free, so you can see the teaching before you pay for any of it. Billed monthly, cancel any time and billing stops.
