“21st Night is a singularly effective studying app. When I use it, my students’ score increases are nothing short of amazing.Trevor Klee, 99th percentile GMAT, GRE, LSAT tutor
If you’re a self-studier, 21st Night will show you what and when you need to study for your exam. Just put in all the questions you have trouble with: copy-paste from a web page, screenshot a pdf, or take a picture with your phone. Once you’re done, click study deck, and your questions will be shown to you at the optimal time to make sure you’re mastering the material.
If you’re an educator, 21st Night will show you what topics your students are struggling with, and help you decide what to focus on next. Create a deck, and assign it to your students, as many as you have. 21st Night will show you their proficiency on each of the questions and topics you assign, both individually and as a group. You’ll know exactly what you need to teach for next time.

Who should use 21st Night?
Tutors who want to target exactly what their clients need to learn without wasting time on notes. Through our collaboration features, tutors can use 21st Night to see their clients’ progress on the problems they assign. Tutors can assign questions, write explanations, and then see how their clients are performing on the questions assigned.
This makes a big difference. Before, tutors had to spend time taking notes on each client in order to provide a personalized experience. This can add 30-60 minutes of work after each session, plus the time at the beginning of the session to analyze how a client is doing on the homework.
Tutors can save time and tutor in a more personalized way with 21st Night. More personalized means happier clients, which means more referrals and more revenue. What’s not to love?
Students who are struggling to progress on a subject or exams. Studying can be overwhelming. It’s difficult enough to keep track of everything you need to know. Then, you’re asked to apply literally all the knowledge you learned on some random question as the clock is ticking down. It’s nerve-wracking!
21st Night presents a better solution. Once you put your questions into 21st Night, it’ll help you learn those questions deeply. Then, it’ll help you remember everything, so it’s as fresh in your mind 6 months later as the day you learned it. When you take the exam, you’ll be ready.

What makes 21st Night so effective?
Most students study for exams by doing question after question. By the time they get to the exam, they’ve done a lot of questions, but they haven’t learned from them.
21st Night works off of a mastery system. It forces students to learn from the questions they found tricky, mastering the concepts they’re weak on. Then, it schedules a review of the question to a later date, so that the concept can pass from short-term memory, to medium-term, to long-term.
As a result, by the time the student takes the exam, they remember the tricks and techniques that every question taught them. It’s all fresh in their mind, just as if they did those questions the day before.
Furthermore, 21st Night gives students analytics on which questions (and which sorts of questions) they’ve been struggling with. It lets them know their proficiency on those questions and categories. With 21st Night’s detailed analytics, students know what sort of questions they need to do next in order to get their goal score.
