jee mains advanced how many marks contained and what is the eligibity for bc candidiated
Hello
If you are qualified in JEE Mains examination then you are eligible for JEE advance examination. If you are BC candidate then you have to qualified with 72% marks in JEE mains examination. And if you are giving JEE advanced examination then you have to score minimum 69 in minimum no of subjects are 6. Then you are qualified the examination. And one thing remember that every year cutoff marks will differ. I'll provide you a link below you can check it for more details.
https://engineering.careers360.com/articles/jeeadvancedexampattern
All the best.
How many marks should there be in JEE Main (March) 2021 to score more than 99 percentile in OBC category?
Hello Dear.
Marks above 150+ can fetch you 99+ percentile it terms of rank General rank above 9,000. As you know the cutoff changes every years because it depends upon the number of seats available, the difficulty level of paper and number of candidates writing the examination hence varies every year depending on these factors. It also depends on home state and other state as you have not mentioned your home state. You can check these details from the link below:

Good Luck
Can I get a seat in IIT or NIT without JOSSA counselling I am a JEE 2021 aspirant
JOSSAA counselling is mandatory to get into IIT NIT.The registration and choice filling process is mandatory for any qualified candidate interested in joining any of IITs,NITs and other GFTIs.Management quota Is not accepted in NIT IIT or any such govt institution.You have to get through counselling only.
Hope it helps
what is exam patternjee advanced (2021 )

Good Luck
I only applied for JEE Mains February session while filling the initial and attempted the paper. Now I am not sure how to pay and apply for the March session. Do I make a new registration? Or as Registered Candidates? Because registered candidates option doesnt show me any option to apply for March
Hello Aspirant,
See till now the application process for JEEMain 2021 March attempt is not started so you are unable to register for March attempt, but don't worry as soon as the application process will start you will be able to apply for it. When the applications for March attempt will get started then you will have to sign in as the registered candidate and then you will get the option to apply for March '21 attempt.
For complete details about JEEMain 2021 Application form kindly check out the link given below :
https://engineering.careers360.com/articles/howtofilljeemainapplicationform
JEEMain 2021 Result for February attempt is expected by March 7th 2021. You can check your result from the link given below :

To have a list of all those colleges which you can get based upon your marks, category, and state you can use JEEMain College Predictor:
https://engineering.careers360.com/jeemaincollegepredictor?icn=QnA&ici=qna_answer
How the final result will be calculated for those who are appearing for more than one attempt of JEEMain 2021 :
> The best out of four JEE Main scores will be taken into consideration for final result.
> All India rank in JEE Main 2021 will be allotted to you on the basis of your best of four percentiles. Let me make you clear with an example, suppose you have got 90 percentile in first attempt, 92 in second, 89 in third and 94 in fourth, so your final result will be made by taking the best result which is of 94 percentile so your final percentile would be 94 and ranking will be given to you according to it.
> As per your category, if you belongs to any reserved category then you will have CRL (Common Rank List) Rank as well as category rank of your respective category.
The final result will get declared after JEE Main May session.

Some insights of JEEMain 2021 :
> To qualify for JEE Mains, there is no minimum aggregate percentage criteria and also if you want to take admission into NITs, IIITs or CFTIs then you should pass in your class 12th. Because as per the latest announcement made by our Hon'ble Education minister Mr.Ramesh Pokhariyal Nishank, the 75% criteria has been removed for upcoming year 202122.
> Also from this year according to New Education Policy the JEEMain examination will be conducted in English, Hindi and other regional languages such as Bengali, Gujarati, Assamese, Kannada, Marathi, Punjabi, Tamil, Telugu, Urdu, Odia and Malayalam.
> In JEEMain 2021 there will be total 90 question out of which you have to attempt only 75 (25 from each section) and there will be two sections for each subject, SectionA will be of MultipleChoice Questions (MCQs)(20 compulsory questions) and SectionB will contain Questions whose answers are to be filled in as a numerical value (10 numerical based questions out of which only 5 are compulsory to be attempted).
> In Section B, candidates have to attempt any five questions out of 10. There will be no negative marking for Section B.
> All question will be of 4 marks and in MCQs there will be negative marking of (1) on incorrect attempt.
This year JEEMain is being conducted with slight changes in it's pattern and it's conduction and you can check out all the changes from the link given below :
