Practice tests

A practice test is written from files you've already saved to your Locker: multiple choice, true or false, and an explanation after every answer. While you're taking it we lean toward the topics you're getting wrong, and when you finish you get a breakdown of where you stand.

Practice tests are part of AI Pro, and so is the Locker they're built from. On Free, and on a current Pro plan, the Practice Tests tab shows "Get AI Pro to unlock this feature" over "Generate practice tests from your own class materials — questions that feel like the real exam, graded instantly.", and closing that leaves you on Duedles, which everyone has. If you've been paying since before Pro and AI Pro split into two plans, your plan keeps practice tests.

Where your tests live

In the sidebar, Locker → Practice Tests. Each card carries the name you gave it, how many questions it holds, when it was made and up to four of its topics. Before you've made one, the tab reads "No practice tests yet". The list starts on Newest First, and the sort beside the button also offers Oldest First, By Class, Best Score, A-Z and Z-A.

Make a test

Multiple Choice and True / False are both on to start with, and you need at least one of them — with neither ticked, the generate button is greyed out. The count runs from 5 to 50 in fives and starts at 25.

Only materials we've finished reading show up in the picker — the ones marked "Indexed" in Materials. A class with none says "This class doesn't have any materials yet. Upload materials to generate flashcards or practice tests." and offers Upload materials first.

While we write the questions

"Generating practice test..." pops up, and a card with your test's name takes its place in the list with a progress bar, "Generating 25 questions..." and a rough countdown. You don't have to wait there: when it's done we say the test is ready and give you a View button, and the phone app sends "Your practice test is ready" if you have notifications on.

Only one practice test generation runs at a time, so a second gets you "You already have a practice test generation in progress. Please wait for it to complete." A flashcard set generating alongside it doesn't get in the way. If one falls over, the card reads "Generation didn't finish. Delete this test and try again."

Other ways to get one

• A finished lecture has Make Practice Test, which builds 20 multiple choice and true or false questions named after the lecture. See Lectures & transcripts.
• Inside a class, Search shows a Practice Test button once you've selected at least one file. It opens the builder for that class, but the files you picked in search don't come with you — choose your materials again there.

Take it

Click a test card. The header carries the name, a count like "3 of 25 answered" and End Test, with a bar underneath that fills as you go.

Each question shows its topic and a line like "Difficulty 3/5". Click an answer, or press its number — the hint underneath reads "Press 1-4 to answer". The verdict lands straight away, with the correct option in green, your pick in red if it was wrong, and an "Explanation:". When we know which file the question came from, it's linked under Sources. Click Next Question, or press Enter.

You get one go at each question in an attempt, and that answer is the one that's scored. Answers save as you go, so stopping halfway still counts toward your topic mastery. Click End Test, or answer everything, and we close with a short results screen — how many you got right on the first try, out of the questions you answered in that attempt — before your analytics open.

When you miss one

After a wrong answer you also get Generate Similar: two more questions on the same concept at the same difficulty, worded differently. They're labelled "Reinforcement question 1/2 — same concept, different phrasing", come with Next Similar and then Continue, and they don't move your score.

Miss a question on a core concept and the header adds something like "Drilling: Cell division". We serve you the questions you haven't seen from that topic while any are left, and the label clears once you've answered two main questions correctly during the drill. A wrong one in between doesn't reset that count.

Your results

Hover a test you've taken and click Analytics, or let a finished test take you there. The top line reads something like "12/25 questions answered across 2 attempts".

Overall Mastery is a percentage and a band: Struggling under 40%, Learning 40% to just under 60%, Practicing 60% to just under 80%, Mastered 80% and up. Under it sits what that's based on, and how many questions you haven't seen yet.

Topic Mastery gives every topic its own card: a score, "4/6 seen", and counts of "mastered", "learned" and "needs work". A question counts as mastered when you've never missed it, learned when your latest answer was right after at least one earlier miss, and needs work when your last answer was wrong. Topics you haven't reached read "Not yet tested".

Topic Coverage draws those scores as a web once three topics have been tested, and Accuracy Over Time appears once two attempts have answers in them. A test you've never taken says "No attempts yet".

Delete a test

Hover the card and click Delete. The confirmation warns that "This will permanently delete this practice test and all attempts. This action cannot be undone." Deleting the class it came from doesn't take the test with it; see Classes.
