How should my first read of an NCERT chapter differ from my revision read?
Reading everything twice at the same speed is not revision. Here is how the two reads should differ in purpose, pace and output.

A lot of you say the same thing: "I have read this NCERT chapter two times and I still lose marks on it." When we ask how the second read differed from the first, the honest answer is usually: it didn't.
The first read and the revision read have different jobs. The first read is meant to build the story of the chapter. The revision read is meant to catch the details that questions are made of: lines, tables, figure labels, exceptions.
Take Photosynthesis in Higher Plants. You can understand the cycle on a first read and still lose marks on which cells hold which enzyme. What does your second read look like, and what do you do with it afterwards?

Use Photosynthesis in Higher Plants as the model.
First read: follow the story. Light reactions in the thylakoid membranes make ATP and NADPH; the Calvin cycle in the stroma uses them to fix . Draw the chloroplast with both sites labelled. Do not worry yet about every enzyme name.
Revision read: go literal. This is where the detail lives. In C4 plants, PEP carboxylase works in the mesophyll cells and forms a four-carbon acid (oxaloacetate); Rubisco then works in the bundle sheath cells. Many students find NEET questions follow NCERT statements closely, so the revision read should be slower and more literal than the first. Underline lines that name a place, an enzyme, a number of carbons or an exception, then build a table from them. Check the current NTA syllabus notice for what is in scope.

Think of it as three passes, each with a different output:
Pass Purpose What you produce 1. Understand Follow the logic A rough chapter map 2. Compress Catch details Tables, flowcharts, a one-page sheet 3. Test Find what has not stuck A list of questions you got wrong Rule of thumb: if your revision read takes as long as your first read, you are rereading, not revising. Revision should be noticeably quicker because you work from your compressed notes and only open the book for the lines you flagged.
Space the passes. Revisit a chapter a few days later, then after a couple of weeks, and so on. A small gap makes recall slightly harder, which is exactly why it works.
Share how you mark your NCERT copy (pencil, symbols, sticky tabs) and what has actually saved time.

Let your mock results choose what to reread. After each mock, open NCERT for every wrong or guessed question and mark the exact line or figure where the answer lives. Your next revision read starts at those marks instead of page one.
A useful split:
What went wrong What the revision read should do Never knew the fact Add it to your table, then quiz yourself Knew it, confused two options Build a comparison table (e.g. two similar processes) Misread the question No reading needed, change your question-reading routine Ran out of time No reading needed, change your strategy Only the first two need the textbook. This stops you from rereading a chapter you already know well.

Repeaters are especially tempted to restart "from page one of NCERT". It feels thorough, but familiar text creates an illusion of knowing: you recognise the sentence, so you assume you could produce it.
Swap the full reread for retrieval. Read a heading, close the book, write what you recall in three minutes, then open and compare. The gaps are your real syllabus for the day.
That said, a full slow read can still be worth it once, if a chapter genuinely feels foreign. Be honest about which chapters those are rather than rereading all of them on principle.

Short blocks help recall reading too. Many students find a break away from the screen after a stretch of focused reading, and stretching or a quick walk, helps more than scrolling. Keep your phone in another room during the block itself.
