JEE Main is a competition-based and high-stakes exam that learners take after completing their Class 12 board exams. National engineering colleges and universities accept the JEE Main scores for evaluating the capability of learners.

After clearing JEE Main, conducted by NTA, learners also become eligible to appear in JEE Advanced.

For getting into NITs and IIITs, a few candidates get some relaxation in JEE Main marks so that they can have equity in educational opportunities. This means SC/ST category candidates have to score lower than the general candidates, considering their historical social-economic biases.

To know more about the JEE Main eligibility marks in 12th for SC and see if learners have to score on different levels, read the following article.

What is JEE Main eligibility marks in 12th for SC?

JEE Main eligibility marks in 12th for SC are the minimum scores that SC students need to be eligible to sit in JEE Main exams.

There is no eligibility criterion or minimum passing marks that learners have to attain in order to take JEE Main. This implies that SC candidates are able to take the test irrespective of their marks in Class12 as long as they have passed their board examination with the relevant subjects.

The Class 12 marks, however, are significant as far as admission in institutions such as NITs, IIITs, and other government-sponsored technical institutes is concerned.

Normally, SC students should have attained a minimum of 65% in aggregate marks in Class 12 board exams, or should have ranked within the 20th percentile of the respective boards.

Class 12 learners should pass in Physics, Mathematics, and one among Chemistry, Biotechnology, Biology, or a technical vocational subject as these are the necessary subjects for appearing in JEE Main.

Understanding the "Top 20 percentile" rule for JEE Main eligibility marks in 12th for SC

After giving the JEE Main exams, only the SC candidates who rank in the top 20 percentile in their respective Class 12 board exams might be able to get admission in NITs and IITs.

Government-funded engineering universities only consider the admission applications of SC learners who get an overall 65% in their Class 12th boards exams.

For JEE Main exams, only passing Class 12 board examinations is enough. This regulation creates educational equity among the learners in boards where scoring high marks is quite difficult.

It particularly applies to the learners who appear in exams under state boards and whose grading pattern can vary dramatically as compared to the central boards such as the Central Board of Secondary Education or the Council for the Indian School Certificate Examinations.

The official percentile cut-offs are released every year, and the applicant is advised to look at them.

JEE Main subject-wise eligibility marks in class 12th

Unlike the 75% requirement for general candidates and 65% for SC applicants for getting admission into NITs and IITs, learners only have to pass in all subjects in Class 12 to sit in JEE Main. There is no minimum subject-wise percentage individually for the eligibility criteria of JEE Main.

In the case of engineering courses, the most preferred three main subjects are Physics, Mathematics and Chemistry (or a similar subject). Weak scores in one subject may impact their overall merit rank and chances of admission in learners' dream universities and colleges.

SC aspirants must strive to achieve good results in all the subjects. Good results in Mathematics are also of great significance since it is a mandatory subject in all fields of engineering.

Number of attempts and age limit for SC in JEE Main

You might now wonder how many attempts and till what age can SC category learners take JEE Main. No age-wise eligibility.

JEE Main can be taken by candidates in the year of their Class 12 exam at any age, and in the 2nd and 3rd year after.

Appearing in two sessions in each year adds to six chances according to the National Testing Agency guidelines.

National and private engineering universities, including NITs and IITs, have variations in admission criteria for each learner.

Relaxation benefits for SC candidates

SC candidates get the following relaxation benefits during admissions in NITs, IIITs, or any other national technical institutes.

1. Lower cut-off scores

One of the primary benefits that SC learners can get as relaxation is in cut-off marks. This means that SC learners with lower scores than general candidates will get admission in government-run institutions after taking JEE Main.

2. Secured seats

The NITs, IIITs, and other centrally funded institutions have fixed percentages of vacancies that are dedicated to SC candidates, according to the government guidelines.

This reservation policy guarantees representation and offers better chances to succeed for learners who have historically disadvantaged backgrounds.

3. Concession in fee

SC candidates have been socially and economically deprived for ages. This is why they are charged lower application fees for JEE Main exams.

They even get scholarships that can contribute hugely to their higher education expenses.

4. Relaxation in ranks during admissions

Joint Seat Allocation Authority suggests that learners of SC background should be given rank relaxation.

This states that during the acceptance of applications, SC learners with low-grade ranks in JEE Main will get the opportunity to study in NITs over General category learners.

JEE Main vs JEE Advanced eligibility: Key differences

JEE Main and JEE Advanced have varied dissimilarities with respect to some major contexts as stated in the table below:

Criteria for DifferentiationJEE Main EligibilityJEE Advanced Eligibility
Exam Conducting BodyNational Testing Agency (NTA)Indian Institutes of Technology (on a rotational basis)
Purpose of ExamAdmission to NITs, IIITs, and other institutesAdmission to IITs
Class 12 Requirement (SC)Only need to pass Class 12 to appearMust have cleared Class 12 with particular subjects and JEE Main
Minimum Marks for Admission (SC)65% aggregate OR Top 20 percentile for NITs/IIITsSC learners should get marks at least as per the minimum cut-off of their respective favorite IITs in JEE Advanced

Selection CriteriaBased on JEE Main scoreMust be among top qualifiers of JEE Main + qualify JEE Advanced
Cut-off Relaxation (SC)Lower cut-off for qualifyingLower qualifying marks in JEE Advanced
Seat ReservationYes (as per government norms)Yes (reservation in IITs)

What happens if you don't meet 65%?

Many SC learners don't score 65% in class 12 board exams. If you are one of them and plan to appear in JEE Main, you can:

1. Check top 20 percentile

In case your score in class 12 is below 65%, you will still have a chance to get admission in NITs and other institutes as long as you rank in the top 20 percentile of your respective board.

This is a great rule especially for learners with tough boards and school curricula. So, check the percentage cut-off of your respective board and see if you are under the 20th percentile group of learners.

2. Improvement exams

In case you fail to qualify in either 65 per cent or the top 20 percentile, then you will be allowed to take improvement exams provided by your board. This is a second opportunity to boost your overall results.

This is an option that works well when you are close to the required percentage and would like to be admitted to the best institutes.

3. Alternative institutes

For SC learners who fail to secure their position in these highly competitive institutions through JEE Main, they can seek out some alternate options. These options include private colleges and universities that admit learners based on other qualifications and internal tests.

Common misconceptions in JEE Main eligibility marks in 12th for SC

There are some myths that prevail among Class 12 learners about their eligibility in JEE Main and concerned scores.

1. Myth 1: SC students need 50% to appear in JEE Main

It is assumed that SC learners require at least 50% marks to be eligible to take JEE Main, but this is a myth.

Similar to any other candidates, SC learners only have to pass in their higher-secondary level exams, and then they can surely take their JEE Main exams.

2. Myth 2: If you score below 65%, you cannot give JEE Main

The 65% criteria is more about an average bar that national institutions like NITs and IIITs set to enrol only the best and most deserving candidates. This is often mistaken to be a criterion for appearing in JEE Main, which can mislead SC candidates.

3. Myth 3: Top 20 percentile is optional

The top 20th percentile includes learners who fall under the bracket of the top 20 per cent learners, and this is not mandatory nor optional for taking JEE Main. It is a different eligibility condition.

In case of failure to achieve the 65% requirement, you have to achieve the top 20 percentile requirement to get admission in centrally funded institutions.

4 practical tips in JEE Main eligibility marks in 12th for SC aspirants

Even though there are some relaxations for SC learners to maintain equality in education, they shouldn't forget to give their best in the JEE Main and Class 12 exams.

1. Also, prioritise board exams

JEE Main exams are extremely challenging for Class 12 learners and require a lot of preparation as well as revision. Besides that, learners should also prioritise their Class 12 board exams.

Focusing on Class 12 board exams can add to your preparation for JEE Main. Many institutes consider your Class 12 board exams as well before admissions.

2. Aim above the minimum

Rather than focusing on only getting the bare minimum marks or reaching the 65% scores in Class 12, aim bigger. There is heavy competition among lakhs of learners who apply for IIITs and NITs, so you must score to be the best possible candidate.

3. Work hard on main subjects

Engineering is based on Physics, Chemistry, and Mathematics.

These subjects require good conceptual clarity that will assist you in passing the board examination as well as the JEE Main.

4. Track official notifications

The eligibility rules and cut-offs might vary with passing years.

To avoid confusion in later processes, stay updated with information on official websites of such agencies as the National Testing Agency and Joint Seat Allocation Authority regularly.

JEE Main eligibility marks in 12th category-wise

The eligibility requirements of Class 12 marks are slightly different in different categories, mostly in terms of relaxation.

1. JEE Main eligibility marks in 12th for OBC

Applicants belonging to the OBC-NCL category normally require obtaining a minimum of 75% aggregate marks in Class 12 or top 20 percentile in their board to be able to be admitted into NITs and IIITs.

2. JEE Main eligibility marks in 12th for unreserved

The unreserved section of the society, as the term suggests, has no eligibility scores for taking JEE Main. Only the 75% criteria and the 20th percentile criteria are fixed for admission in NITs after giving JEE Main.

3. JEE Main eligibility marks in 12th for ST

Scheduled Tribe (ST) applicants have no criteria for eligibility for JEE Main. Like SC applicants, ST student applicants are required to have the required 65% aggregate marks or be among the top 20th percentile.

4. JEE Main eligibility marks in 12th for EWS

The EWS category candidates share the same standards as the general category for marks qualification.

This means that they usually have to score 75% aggregate marks or 20th percentile. EWS has a separate reservation quota (10%) with relaxed cut-offs in counselling.

Why the eligibility criteria matters

The eligibility criteria in JEE Main matter because the reasons are as follows:

1. Academic foundation for engineering

The engineering profession is quite challenging. Therefore, one must have a good understanding of Class 12 core subjects.

The top 20 percentile or 65% marks eligibility criteria reinforce that learners have to strengthen their foundational knowledge in Class 12 itself, before going to highly resourceful colleges.

2. Fair comparison across different education boards

There are various education boards in India with different levels. The top 20 percentile rule makes a fair platform for all learners with respect to their boards instead of depending entirely on percentages.

3. Equal opportunities

General category learners get the opportunity to study in NITs and IIITs when they score at least 75%, while 65% scores are enough for the SC students. This is only to create equal opportunities and pull the disadvantaged sections from years of bias and social deprivation.

Summing up

The JEE Main eligibility marks for SC learners are 33% marks in Class 12 overall results, which means learners just need to pass. This is enough eligibility.

The top 20th percentile ranking and 65% in Class 12 is considerable when getting into national-level engineering universities. This shows Class 12 results are a deciding factor for achieving your final goals of studying in IIITs and NITs.

So, apart from being concerned and focused on JEE Main, put hard work into the preparation of Class 12 board exams as well.
