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.

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.
- Carry out domestic gas heating and hot water system design
- Carry out work on unvented hot water storage operations
- Commission new and existing gas systems, installations and components in industrial properties
- De-commission gas systems, installations and components in commercial properties and leisure accommodation
- De-commission gas systems, installations and components in industrial properties
- Design domestic gas systems for the installation of appliances or components

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.

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.
