The problem
Hours of studying are not the same as being ready
Passive studying
Rereading, highlighting and watching videos feel like progress, but they never make you solve anything on your own.
You find out too late
Only on exam day do you discover you weren't prepared, when there's no time left to fix it.
Training without proof
Companies train their staff but can't objectively verify what each employee learned, or whether they're ready for the job.

How it works
From your material to a practice exam, in three steps
- Step 1
Upload your material or pick a topic
Paste text, upload a PDF or start from a topic. You can also use our database or search the web.
- Step 2
Choose how many and a difficulty from 0 to 9
Decide how many tests and exams you want, and at what level: from simple questions all the way to olympiad level.
- Step 3
Practice with guided tests, then take timed exams
First you practice with step-by-step help; then you put yourself to the test against the clock, with no help.
Two modes
One mode to learn, another to prove what you know
To prove it
Exam
Timer, no help
- All the questions at once
- Timed
- No help of any kind until you submit
- Harder: it covers all the material
- Submits itself when time runs out
Why Examinz
You learn more by practicing than by rereading
Answering, making mistakes and correcting them before the real exam is active learning: what you learn this way sticks better than what you only read.
