What a night can do is find your weakest topics and fix the ones that are fixable. Here is the plan, in order.
WeSolve+ reads the whole document and writes the questions for you
Upload your PDF, photograph your notebook, or point the camera. WeSolve+ writes questions from that material, explains why each answer is right, reads the chapter back to you as a podcast, and remembers every item you missed until you own it.
The tool below is a small browser-only tool and it is not WeSolve+: paste a few lines and text rules turn them into cards on the spot. The real app, the one that uses AI, is behind the link above.
Quiz maker
This tool runs only in your browser, and that is all it isIt splits the text you paste by rule, and nothing else. WeSolve+ is a different thing entirely: it reads your whole PDF with AI, writes the reasoning behind every question, speaks the chapter back to you, and remembers what you missed so it can return it. Try the real app now, free!
This tool uses text rules, not AI. It looks for lines written as "term: definition" or "term = definition" and makes a two sided item; for any other line it removes the longest word and asks you to supply it. Your text stays in the browser and is never sent anywhere. The copy button produces tab separated rows, the format Anki and Quizlet both accept.
Who it's for, and who it isn't
Your exam is tomorrow and you have the lecture PDFs or photos of your notes. Upload them and within seconds you are answering questions instead of rereading, and the misses show where tonight's hours should go. If you have no notes or slides at all, the app has nothing to question you on. Nor will it work through math problems step by step. Free gives you two quizzes and two PDF uploads today. Premium is ₺299.99 monthly on the web, or ₺99.99 for a single week; the App Store shows your currency.
Say it plainly: one night is not enough
Cramming works for tomorrow and fails for next month. Material learned in one sitting fades faster than material reviewed on several days, a pattern researchers call the spacing effect. So tonight is damage control. If the course has a final later, plan to see tonight's material again in a few days, because that return is where most of the lasting learning happens. For tonight the aim is narrower: walk in tomorrow knowing which topics you can answer, with as many of the rest fixed as the hours allow.
The first thirty minutes: test before you read
Do not open the notes and start at page one. Gather what the exam covers, split it into topics, and quiz yourself on every topic before rereading anything. With WeSolve+, upload the lecture PDFs or photos and take a short set per topic; on paper, use last year's paper or the review questions. Mark each topic green, yellow or red by how you did. The rereading you skipped is time you now get to spend on the red topics.
The middle of the evening: fix the red, then the yellow
Start with the red topics, and for each miss read the explanation and the source sentence before anything else. Most misses have a cause you can name: a term you confused, a step you skipped, a question you read too fast. Fix the cause, then write one line about it on a sheet of paper. After an hour on red, move to yellow. Leave green alone; rereading what you already know feels productive and changes nothing tomorrow. Take a short break every hour, away from the screen.
What our data says about a first round
In the WeSolve+ study data, drawn from 1,790 questions answered between 24 August and 29 September 2026, students got 55.9% right overall. So expect your first set tonight to look bad and do not panic at the score; it shows you where to spend the evening. The same data found 49.6% of wrong answers came from a misunderstood concept, which is why the middle of the evening goes on reading explanations rather than drilling the same questions.
The last hour, and the morning
Retest the red and yellow topics with fresh questions rather than the ones you have seen, so you measure understanding instead of memory of the question. Then stop at a set time. Sleep plays a part in holding on to what you learned (see sleep and memory), and an all nighter trades tomorrow's clear head for an hour of tired reading. In the morning, spend fifteen minutes on your one line notes and a handful of questions, then eat and go. The exam morning routine covers the rest.
A quick check without uploading anything
If all you have left is a list of definitions, paste it into the quiz maker on this page. Lines written as "term: definition" become two sided items, and every other line loses its longest word for you to supply. It runs in the browser on plain text rules with no account, which makes it a fair five minute warm up before bed; whole PDFs and explained answers need the app. With a full day rather than a night, our guide to studying for a test in one day sets out a longer triage.

Is it worth studying the night before an exam?
Yes, if you use the time to test yourself and fix weak topics rather than reread everything. It will not replace review spread over several days, and material learned in one night fades quickly, but a focused evening can still move tomorrow's result.
Should I stay up all night before an exam?
Better not. You trade a few extra hours of tired reading for a slower, less focused mind in the exam room. Set a stop time, retest your weakest topics before it, and keep fifteen minutes in the morning for a last check.
What should I study first the night before?
Test yourself on every topic before rereading anything, then start with the topics where you scored worst. Reading from page one spends your freshest hours on material you may already know, and leaves the weak topics for when you are tired.
How far ahead should I really start?
For lasting results, a week or two, with short reviews spread across the days. Research on the spacing effect shows that spaced reviews last longer than one long session, and a single night rarely leaves room for more than one or two passes.
