Practice test 3 · Question 14
You likely dropped a minus sign when moving terms to the other side. Redo the second line, then try two similar questions on composite functions.
Early access · Android tablet beta · v1.1
Reviewly is a tablet study app for students preparing for university entrance exams. Solve your test books on screen, check them against the answer key, and keep every mistake in one place, ready to review, with AI guidance on the way.
Every YKS student knows the yanlış defteri, the notebook where you copy out the questions you got wrong. It works, but it eats hours. Reviewly keeps the habit and drops the copying.
How it works
Open your test book on the tablet and tap your answer right on the page. The app finds the A–E choices on the device, and you can fix any it misses.
In betaEnter the book's answer key once. Reviewly compares your answers and lists every one that doesn't match, so nothing slips through.
In betaCome back to your wrong answers before the exam. AI help will explain why the right choice is right and what to practise next.
PlannedWorks with the PDF test books you already own, imported straight on the tablet.
From the current beta
These come straight from the v1.1 beta build: your books in one library, and a tap-to-fill answer key for each book. Every book gets its own list of wrong answers.
Screens rendered from the beta build with test data. Interface text is still partly English.

Privacy
Your test books, answers, answer keys and notes are stored on the tablet. No account, no cloud sync.
Anything that leaves the tablet is off until you switch it on. Today that's one feature: server reading of printed question numbers, which sends only the page image it needs.
We never host, share or resell your test books. You use the books you already own, on your own device.
Where we are
Built for Android tablets and tested on the Samsung Galaxy Tab S8 with S Pen.
We're opening the beta to a small group of students, parents and teachers. Send us a note with your exam and your tablet model, and we'll be in touch.
