AI Engineer
Build, ship and run systems with a model inside them — from the first prompt to the GPU cluster it eventually needs.
This is an order, not a shopping list. Each step assumes the one above it. Sitting a professional-level paper before you have the hands‑on months behind you produces a low score and no useful diagnosis — the questions test judgement you have not had the chance to build yet.

2 examsThe AI Engineer ladder is 7 exams. Sat end to end that is about 11.5 hours of exam time, which is the part most plans underestimate: the reading is not the constraint, the clock is. The order is not decoration. Each stage assumes the vocabulary of the one before it, so sitting them out of sequence usually means learning the same material twice — once badly, in the wrong context.

What a AI Engineer mock test gives you
The published blueprint, not an approximation
The question count, the time limit and the weight of each domain are read from each awarding body’s own exam guide. If a domain is worth 30% of the real paper, it is worth 30% of the mock test.
A score report that names the weak domain
Every mock test ends with a per-domain breakdown against the official weighting, and the reasoning for each item you got wrong — including why the answer you picked was wrong, not only why the right one was right.
A different paper each time
Sitting a second mock test does not mean seeing the same questions again. Each is drawn fresh against the blueprint, so a repeat measures preparation rather than recall.
Real timing, including the pressure
The clock, the question palette, flagging and review all behave as they do in the exam room. Running out of time in a mock test is the cheapest way to find out you would have run out of time.
Questions people ask
Do I have to sit these in order?
No, but the ladder is built the way it is because each stage assumes the one before it. Skipping ahead usually means covering the same ground twice.
How much exam time is the whole ai engineer path?
About 11.5 hours across 7 papers, not counting the preparation between them. Practising against the real clock is the only way to find out whether that is realistic for you.
Can one pack cover the whole path?
A pack is bought against a category, and a path can cross categories. The pricing page shows which category each exam belongs to.
