It means that roughly 80% of your exam score can come from just 20% of the syllabus/topics, the weightage areas.
It implies you should identify the small set of chapters or question‑types that frequently appear and carry most of the marks.
It suggests that you should allocate most of your effort and time to those 20% rather than trying to cover everything equally.
The rule doesn’t explain that you should avoid the remaining 80% entirely; rather, you cover them to a lesser extent while you give more time to the 20%.
It’s an important part of preparing efficiently, helping you focus on what improves the JEE Mains performance.
Know the JEE Main High-weightage Topics
Give time to the chapters that give you the maximum marks in Physics, Chemistry, and Mathematics, thus increasing your marks and concentrating your efforts on these 20%.

Check JEE Main Previous Years’ Papers
Practice past JEE Mains papers, highlighting repeatedly asked questions and frequently asked concepts, and give time to those topics and concepts during preparation.
Prioritize Your Strengths
Focus your study effort on topics that you are familiar with or do well in, as they will give you the maximum score. The weak topics can be reviewed in order not to lose easy marks.
Practice Smartly
Work through conceptual questions and application-based questions from the topics with high weight. Do not spend excessive time on questions from chapters that are low-weightage.

Time Management in JEE Main Preparation
Your study hours should be balanced in such a way that your most study time will be spent on high-weightage and least amount of time on the low-yield.
Monitor Your Progress
You should keep a record of every topic performance in a test and use it to see your preparation strategy each time you take a test to monitor what preparation area gives you the maximum improvement result.

Here we will break down how to apply the 80/20 Rule in JEE Mains. You can check it below:
The 20% in the 80/20 Rule means the small effort that generates the majority of results - in this instance, scoring high on JEE Mains. Since studying is such a large part of our daily routine, with too many tasks on our list, we want to be able to determine the movements that will give us the best results. Here is how you can identify your 20%:
Identify Goal
First, identify the score or performance goal for JEE Mains. When you are clear on your target performance goal, you can identify what the value of higher-impact activities really are.
Examine Study Routine
Review your daily and weekly study behaviors. If you study five times a week and you try something you believe adds value, but after analyzing, it does not add value, then you could use that time for higher-value behavior. When you review study behaviors, examine actions you believe are higher-impact or lower-impact.
Focus on Those 20% Tasks
After identifying your high-impact tasks, all of your time and effort should be devoted to those high-impact tasks. It is obvious that low-impact tasks take time away from high-impact tasks; therefore, low-impact task time should be summarized, evaluated, or minimized altogether.
Recheck and Adjust
As you get closer to exam day, your priorities may shift. You should recheck your high-impact tasks for that day or in your study plan.

JEE Main Chapter-Wise Weightage
Once you know your 20% high-impact tasks, the next step is to identify the 80% of tasks that are least impactful in achieving those results. These 80% activities are time-consuming yet produce minimal points.
Identify Low-Impact Tasks
Look at the services that take the most time but add the least value, for instance downloading study material, re-organizing your notes for the hundredth time, and browsing the web.
Minimize Ineffective Activities
Be concerned about the amount of time you devote to the low-weightage activities. By limiting this time, you can spend more time focusing on the 20% of tasks that are most significant.
Differentiate
If you can, differentiate low-value tasks. Then it will be easier to prioritize your work and focus on what will matter for your core preparation for the test.
Constantly Recheck
These 80% low-impact tasks will change over time. In other words, it is important to check and schedule your study and your tasks.
Frequently Asked Questions (FAQs)
No, you should study the remaining topics minimally to make sure you don’t lose marks, but focus majorly on the high-weightage areas.
Check past years’ papers, mock tests, and repeatedly asked questions in Physics, Chemistry, and Mathematics.
It means that roughly 80% of your marks can be achieved from 20% of the syllabus.

HELLO,
The JEE Main application verification system uses the name you enter in the application form at the time of Aadhar Card verification so if you your Aadhaar was updated but still it is showing name not verifies then it means the new details have not been reflected in the online system use by NTA
Now what you can do is :-
1. First check the status of your Aadhaar card updates on the official UIDAI website by using your Update request Number.
2. Verify the details you have entered in application form like ensure that the name that you have entered in the JEE main application form exactly matches your newly updated Aadhaar card
3. You can use the NTA Mismatch Advisory like if a name mismatch pop up appears during the application process so for this NTA has provided the solution first close the pop up then a new window will appear that will allow you to enter the name exactly as it is on your Aadhaar card
4. If still the problem does not solve then you can contact the NTA Helpdesk

Hope this Helps!
While filling the form of JEE Mains 2026 January session, upload the improvement marksheet, as your improvement marksheet is your final marksheet of class 12th AISSCE exams. The one that you got before the improvement doesn't matter now as you appeared for the compartment exam to increase your overall score. So, use the marksheet given to you after appearing for your improvement exam everywhere as that is your finalized class 12th marksheet.
Hello, Yes, this mismatch will absolutely cause a problem during your JEE Mains 2026 registration, but there is a clear solution.
You must enter your father's name "Girisharadya" (without the 'a') in the main application form, as it appears on your 10th-grade marksheet. The 10th marksheet is the primary, non-changeable document for all NTA applications.
When the system tries to verify this with your Aadhaar, it will detect a mismatch ("Girisharadya" vs. "Girisharadhya") and will show a pop-up warning. NTA has created a process for this: you will be given an option to enter your father's name as per your Aadhaar in a separate field. The system will then capture both spellings, allowing you to complete the registration.
However, since you have time before 2026, the safest and most highly recommended solution is to get your Aadhaar card (and your father's) corrected to match the spelling on your 10th marksheet ("Girisharadya"). This will prevent any confusion or problems later during JoSAA counselling and final document verification.
I hope you found this information helpful and for any study related queries you can ask in careers360 app, Have a great day!
Hello Aspirant,
Jee main's high scoring chapters:
For mathematics : Coordinate Geometry, Calculus (especially Integral Calculus), and Algebra (Complex Numbers, Quadratic Equations, Matrices, Determinants) .
For physics: Thermodynamics, Current Electricity, Electrostatics, and Optics.
For Chemistry: Periodic Table, Chemical Bonding, Hydrocarbons, and Chemical Kinetics.
This chapters are the highest scoring in jee main. Hope this will help u. Wish u good luck.
Hello,
If you are currently studying in Class 12 and haven’t yet received your registration number or roll number from your board, you can leave that field blank or enter “NA” (Not Applicable) in the JEE Main application form.
Once your board issues the official registration or roll number, you don’t need to worry, NTA verifies your board details later during counselling or admission, not during registration.
So, do not enter random numbers, use “NA” or skip if optional.
Hope you understand.
