What is free, and what a full bank costs
The free tier is a real one, not a teaser. Paying unlocks the depth: every question in a certification's bank, drilled one objective at a time, and mocks weighted like the real paper. A certification costs $200 to take, and a retake is another $200.
Three tiers
Free
$0 no account needed
Ten practice questions per certification, with every explanation shown, plus every study note. Full mocks and objective drills are paid.
- Ten practice questions per certification
- Every explanation, right and wrong options alike
- Every study note, one per exam objective
Per certification
$19 once, permanent
Unlocks one certification's full bank, drills, and weighted mocks, for good, including questions added to it later.
- Unlimited untimed drilling, objective by objective
- 2 guaranteed-fresh full mocks
- Every explanation, sourced from the vendor's own docs
Every certification
$49 for 12 months
One charge covers every certification we publish, including ones not live yet, for 12 months from purchase. Not forever: a growing catalogue for one payment would only get worse for us to keep honoring.
- Everything in the per-certification tier, for every track
- Covers a certification the moment it goes live
- Still well under one $200 exam fee
Both prices are in USD and include any VAT or sales tax, so the amount shown is the amount charged, wherever you are.
Access is opened by hand while we're pre-launch, free for now: sign in and ask, and it is granted. No charge yet, and these are the prices once that changes.
Dated, not evergreen
What you are paying for is content that is current, so here is the narrow version we will stand behind, and what it does not cover.
What we do claim
- Every item is written against that certification's current published exam guide, and the guide's own date is printed on this site.
- Every explanation links the vendor's own documentation, and a link that stops resolving is repaired or dropped.
- When a vendor renames something, we rebuild the item instead of quietly leaving the old name in place.
What we do not claim
- That these are real exam questions. They are not.
- That a score here predicts a score there.
- That the bank is complete on day one. It grows, and your access covers what is added.
