Practice modes
Four ways to practise, one question bank
Every mode takes a difficulty filter: Easy, Medium, Hard or Mixed. Mixed targets a 30/40/30 split, the same as the bank itself.
⏱️
Exam
Full length, domain-weighted, with the official item count and a countdown that auto-submits at zero. Nothing is revealed until you finish. Then you get a scaled score, pass or fail, and a per-domain breakdown.
Exam-day rehearsal📖
Study
The same questions without a clock. After each answer you see the verdict and the full explanation, then move on.
Learn as you go🎯
Domain drill
Pick one or more domains and a difficulty, and practise only those, with inline review like Study mode.
Fix a weak domain🔁
Weak-area review
Brings back only the questions you've got wrong before, starting with the ones you've missed most often.

Features
Built to get you across the pass line
No repeats
Questions you haven't seen come first, so each attempt draws fresh items until the bank runs out. Answer options are also shuffled on every attempt.
An explanation for every question
Every question has four options and a written explanation of why the right answer is right.
Readiness tracking
Best, average and last score, your exam-mode pass rate, and a clear Ready / Not ready verdict for each exam.
Progress across exams
A dashboard showing performance over 30 days, 90 days or all time, your best score against the pass mark, and recent activity.
A real exam runner
Flag questions for review, jump around with the question grid, and keep an eye on the timer, just as in the testing centre.

Scoring
A score on the scale the exams use
Results are reported on the 100–1000 scale most vendors publish, so the pass line you practise against looks like the one you'll see on exam day.
score = 100 + 900 × correct ÷ total
With a 720 pass mark, that works out to about 69% correct. Unanswered questions count as wrong. After an exam you also get a breakdown by domain and by difficulty, plus every missed question with the correct answer and its explanation.
This is a model of a scaled score, not the vendor's own equating. Treat 720 as a training target and aim to clear it comfortably.
