Daily general knowledge quiz

How to play

1. Press Start today’s quiz. Everyone who opens this page on the same date gets the same 10 questions, and a new set starts at midnight, your time.
2. Pick one of the four answers. The right answer, a short explanation and the lesson the question comes from appear straight away.
3. Press Next question to move on, and See your score after the tenth.
4. Press Copy your score to share it. The copied text has the date, your score and a row of squares, filled for a right answer and empty for a wrong one, so it gives nothing away.
5. For more, press Play a random round. It deals 10 different questions from the same pool.

There’s no timer and no sign-up. If you come back later the same day, the page shows your score and lets you look through your answers again, instead of dealing a fresh set.

How the daily round is picked

The quiz draws on a pool of 64 questions: 8 from each of the app’s categories (Psychology, Tech & Internet, Business, Money, History, Science, Philosophy and Productivity). We leave out questions that only make sense next to their lesson text, and lessons we’ve flagged for a correction.

Your device’s date becomes a day number, with November 1, 2026 as day 0. The questions in each category are shuffled with a seeded random number generator, the order of the categories is shuffled too, and the questions are then dealt out one category at a time. Any 10 questions in a row of that deal include all 8 categories, so every daily round covers every topic, with two topics getting a second question. Day 0 gets questions 1 to 10, day 1 gets 11 to 20, and so on. After 6 days, which use 60 of the 64, the seed changes and the deal starts again in a new order.

The four answer options are shuffled as well, using the date and the question, so everyone sees the same order on the same day. Across the app’s 1,753 quizzes the right answer is already spread evenly (A in 25.0% of them, B in 24.6%, C in 25.6% and D in 24.9%), and the shuffle keeps any one day from bunching answers on one letter.

Your score is the number you got right out of 10, with a line for each topic. Say you get 7 right. The result shows 7/10, and the copied text reads “Scroll daily quiz” with the date and your 7/10, above a row of 7 filled squares and 3 empty ones.

Play the daily round on consecutive days and the page counts a streak. Miss a day and the next round starts it again at 1. Random rounds don’t count toward it. The score and streak are kept in this browser only, so clearing your site data resets them.

Where the questions come from

Every question is the quiz at the end of a lesson in Scroll. In the app you read the lesson first (21 to 115 words, with a median of 69) and then answer from memory. Here you meet the question cold, so some will be harder than they’d be in the app. The question, options and explanation are shown as the app has them, which is why a few use British spelling and lesson titles keep their capitals.

After each answer you’ll see “From the lesson” with the lesson’s title and a link to more lessons in that category on this site. The history lessons page and the other category pages show a few lessons in full, with the rest listed by title.

Why each answer comes with an explanation

Answering a question and then checking the answer is a form of practice testing. A 2013 review of 10 popular study techniques by Dunlosky and colleagues rated it one of only two with high utility; the other was spacing out study. In Henry Roediger and Jeffrey Karpicke’s 2006 experiment, students who took a recall test on a prose passage instead of rereading it remembered 56% of it a week later, against 42% for those who reread, even though rereading made students feel more confident.

Rowland’s 2014 review pooled 159 effect sizes and found that testing beat restudying by a medium margin (Hedges’ g of 0.50), and by more (0.73) when people were told the right answer afterward. A g of 0.50 means the average person who was tested scored higher than about 69% of the people who restudied. Most of these studies used students and lab materials, effects varied a lot between studies, and none of them tested this quiz or the Scroll app.

That’s the reason this quiz shows the answer and the explanation after every question, whether you got it right or not.

How we check the questions

Each lesson in the app names its source, and we compared lessons against primary sources while building the site’s tools in October 2026. Ten lessons in the main feed made claims we couldn’t match to the evidence, among them lessons on ego depletion and the marshmallow test. Those 10 are kept out of this quiz until they’re fixed in the app.

That check didn’t cover every question in the pool, so mistakes are still possible. Each question has a “Report a problem with this question” link, which opens an email to us with the question’s id in the subject line. When a lesson is corrected in the app, the fix reaches this quiz the next time we copy the lessons over.

What your score doesn’t tell you

A score says which of these 10 questions you knew today. It doesn’t measure intelligence or memory, and topics vary in difficulty: someone who reads about money will find those questions easier than the philosophy ones. Questions you’ve met before, in the app or in an earlier round, are easier the second time.
