  • A major change has been announced in the JEE Main 2020 exam pattern with reduction of number of questions, changes in marking scheme and total marks. Numerical questions have been introduced for Maths, Physics, Chemistry while Paper 2 has been clearly demarcated for B.Arch and B.Plan students.
  • Total number of questions have been reduced to 75 from the earlier 90 questions for Paper 1. Negative marking has been removed for numerical questions such that 15 questions for 60 marks in Paper 1 have no negative marking.
  • B.Arch applicants have to appear for drawing while B.Plan aspirants attempt questions on planning.

Candidates can appear twice for JEE Main 2020 -January and April. The JEE Main application form for April session will be available from February 7 to March 7 with download of the admit card from March 16. The JEE Main April session exam will be held from April 3 to 9 with result declaration on April 30. The better of the two scores will be used for the purpose of ranking as per the regulations laid by the authorities. States like Odisha, Madhya Pradesh, Haryana, Uttarakhand, Bihar, Jharkhand and Nagaland as well many other private universities and institutes use JEE Main ranks for admissions; however, admission criteria for these will be notified by the concerned authorities only.

  • Thereafter for every round after the allotment, candidates who are allotted seats must download the provisional seat allotment letter, pay the part seat acceptance fee and report to the nearest reporting centre as specified for verification of documents.
  • Next they must take the freeze option if they wish to keep the seat and not participate further; float option if they wish to upgrade in the next rounds and slide if they like the institute but wish to upgrade to a better branch within the same institute.

After the last round is completed, candidates mut report to the institutes to complete their admission formalities by paying the balance fee and submitting the requisite documents to the allotted institute.

how to calculation a percentile exam of jee

Sonali Sahu Student Expert 20th Oct, 2019


percentile calculation depends on how many number of students has appeared the exam in the current year. Your score will be used and it will say where you stand in this competitive population.

For eg:-  let 100 candidates have given the exam and you have score around 280 from 360. then there are many candidates who score from -ve marking to 270 and many candidates who have score above 281-360. lets take there are 30 students above you that means there are 69 students below you which makes your percentile 70.

if there are 5 candidates above you than your percentile is 95 and thee are 94 candidates who have scored below you and 5 candidates who have scored above you.

in reality it not 100 in number, it is above 10 lakhs candidates so your percentile will get affected accordingly. so try to score as best as you can. the higher you score there are many chances to get less people above you.

Hope it helps!

only two months are left for jee mains January attempt exam how should I prepare for it?

Apurv 19th Oct, 2019

Hello Mitali, the best way to prepare would be revise the topics that you already know and make that even stronger, so that you don't at least miss questions from that. Then, you should focus on Inorganic chemistry which has a weightage of about 35-35% in JEE Mains, so you can start memorizing in the last 2 months. You can prepare for some of the topics of 11th class, because those are easier.


can i easily get into NIT? I am pwd candidate taking jee coaching

Ronak Gala Student Expert 19th Oct, 2019

It means you are General Person with disabilities candidate and for you people 3% seats are reserved. And in practically it gives you great chance to get a seat in any government field (May be not in defence).

Cut off marks of last year JEE mains

Unreserved general category had eligibility cutoff as 74 marks in JEE mains where as GENERAL PWD had 19 marks as cutoff... So you need to score 80 and above.. To be on a stage to crack NIT.

See for Gen PwD it is just 19 marks means if you correct just 5,6 questions then you will clear JEE mains and for just Gen they need to correct at least around 30 questions to clear JEE mains. Hope you getting this difference. But i suggest you do not take it as advantage and study less.. Please study well and try to get such marks that you do not need any type of reservation to get any seat.

Best wishes. Thank you.
