It certainly feels like it.
Nearly everyone does it. You read the chapter, and then, just to be safe, you read it again. So let us watch two people study the same chapter, and see what happens on Sunday.
Same class. Same chapter. Same Friday evening. Same mother asking, twice, whether they have eaten.
Kabir reads the chapter twice. The second time goes faster. Every heading looks familiar, every diagram makes sense, and he closes the book feeling like a person who has studied.
Riya reads it once. Then she closes the book and writes down everything she remembers. She gets about half of it. She stares at the empty half of the page for a while. She does not feel like a person who has studied. She feels like a person who has been insulted by a notebook.
Friday. Kabir reads it twice.
Friday. Riya reads it once, then writes what she remembers.
On Sunday, a friend asks them both: “So, what was the chapter about?”
Sunday. Kabir.
Sunday. Riya.
Kabir can feel the chapter in there somewhere. It will not come out. Riya does not remember all of it either, but more of it comes out, because on Friday she already practised the one thing Sunday asked for: getting it out.
Kabir was not lazy. He did more reading than Riya. He just practised the wrong thing.
Your memory can do two different jobs. It can recognise: you see something and know you have seen it before. And it can recall: you bring it back with nothing in front of you.
Think of your best friend's face. You would know it anywhere, in any crowd, from the back of a moving bus. Now draw it from memory. (Please do not show them the drawing. You would like to keep the friend.)
That gap, between knowing a face and drawing it, is the gap between re-reading a chapter and answering a question on it. Re-reading trains recognition. Exams ask for recall.
Every time you re-read, the page gets more familiar. And familiar has a trick: it feels exactly like known. This trick will follow you through the whole course, so it deserves a name. Call it the Familiar Feeling.
The Familiar Feeling loves solved examples. You follow each step. Each step makes sense. So it feels as if you could have done it yourself. Then you meet a blank question and cannot start. Following is recognition. Starting is recall.
It is the same reason that watching someone roll perfectly round rotis on YouTube, ten times over, does not make yours round. Your rotis find out the truth the first time you try. So does the exam.
Learning anything has two halves. The first is getting it in. Scientists call this encoding: your brain saving something. The second is getting it back out when you need it. That is retrieval, or recall. They are not the same job, and practising one does not fully practise the other.
Here is how the saving happens. Your brain is made of billions of cells called neurons. A memory is not kept inside one of them. It is a pattern of connections between many of them. When the same cells fire together, again and again, the connections between them grow stronger, and the pattern becomes easier to fire the next time. Neuroscientists have a short way of saying it: cells that fire together, wire together.
So repetition works. Re-reading is repetition. The question is what, exactly, it repeats.
When you re-read, you always start from the book. The page shows you the words, and your brain walks from the page to the idea. Do that five times and the road from the book to the idea is wide and smooth. But on Sunday, and in the exam hall, nobody hands you the book. They hand you a question. And the road from the question to the idea is the one Kabir never walked.
Every time you pull an idea out, starting from a question, a blank page or a friend asking, you walk that second road. Each walk makes it a little easier to find next time. That is what Riya was doing on Friday, even though it felt terrible.
There is a bonus. To get an idea out, you usually have to go through what it is connected to: the example, the reason, the step before it. So the idea stops being a thing sitting in storage. It becomes something you can use: on paper, in a question, in your own words.
In a 2006 experiment, US university students learned the same material in two ways: by studying it again, or by testing themselves on it. On a test five minutes later, studying again did better. On tests two days and a week later, testing did better. And the students who studied again felt more confident that they would remember.

Re-reading wins the first five minutes and loses the week. And the whole time, it feels like it is winning. That is the Familiar Feeling at work.
There is an old saying: I hear and I forget. I see and I remember. I do and I understand. It is usually credited to Confucius, who never said it in those words. Its oldest known form comes from Xunzi, a later Confucian thinker, who put doing above everything else. The saying needs one small correction from this page: seeing mostly lets you remember that you saw it. Hello again, Familiar Feeling. The understanding is in the doing. Here is the doing.
This takes about as long as reading the chapter twice. It will feel slower, because it is harder. Harder is the point.
For a solved example, in maths or in reasoning: cover the solution and try the first step yourself. Uncover one line only when you are truly stuck. The next day, solve the same question again from a blank page. Keep coming back to it until the solution comes to you easily, the way the next line of a song you know does.
Or explain it out loud, without the book, to a friend or a younger brother or sister. They do not need to understand it. They do not even need to be listening. The place where you get stuck is the part you have not learned yet.
At first, yes. The blank page will be emptier than you expected, and nobody enjoys that. Re-reading felt good because it never showed you the gaps. This shows you every one of them.
The gaps were always there. Now you can see them, and a gap you can see is a gap you can fix. If you want to stop in the first week because it feels like you are learning less, remember the experiment: the students who studied again felt more confident, and remembered less a week later. Be Riya. Be annoyed. It passes.
Sometimes what feels like exam nerves is the moment, in the hall, when you find out that you did not know it. Testing yourself moves that moment to your desk, where there is still time to fix it.
No. Ratta is repeating words you do not follow until you can say them back. Recall is different. You pull out, step by step, something you have understood, and then you check it. Each time you do that, you understand it a little better.
Understanding is not a switch that turns on in class. "I understood it when the teacher explained it" is the first step, not the last one. You find out whether you really understand something when you try to do it yourself, with nothing in front of you.
And if you are still worried that recall only helps you repeat things, someone tested that too.
In a 2011 experiment, US university students studied science texts. Some practised recalling them from memory. Others studied them again, or drew concept maps, which means organising the ideas into a diagram. A week later, the recall group did best, including on questions that asked them to reason with the material, not repeat it.

Kabir tries the blank page. He gets about a third of the chapter. He is annoyed, and he tells the notebook so, out loud.
The next Sunday. Kabir.
On Sunday, the friend asks again. Not everything comes out. But something does, and Kabir notices a feeling that is different from the familiar one. The chapter is not just in there somewhere. He can find it.
In the app, you answer every question before you see its solution: a small blank page, every time. On harder questions, it also asks, “How did you solve this?”, because, in the app's own words, “Putting your reasoning into words strengthens it in your mind.” Then it shows its own reasoning and asks whether your method matched.
