if i failed in one subject in 12th cbse

You might have heard someone or the other day that they had failed their CBSE 12th boards in one subject.

As spectators, we can only imagine their anxiety, stress, frustration or fear about those upcoming days.

Well, CBSE has their own student-friendly rules that can save these children from actually failing 12th class and repeating that year.

You can go through the following article to first understand the CBSE’s rules for failing one subject in class 12, and then give assistance for academic as well as emotional support.

What Happens If You Fail in One Subject?: Understanding CBSE’s Rules

CBSE is a board of education that controls our curriculum , syllabus, and conducts exams in our country.

If you fail in one subject in exams of class 12 boards, CBSE gives the right to write a compartment exam. Instead of declaring these students as failed, the result shows as a compartment.

Failing in one subject means only compartment and not failing in the whole 12th class or session.

As per CBSE official website, once these learners achieve their pass marks in that one failed subject, their marksheet shows the final pass marks as a regular marksheet

These compartment exams are conducted in the same as well as in the coming year for maximum 3 times till not passed. First in July (immediately after results), then 2nd attempt in the next year (March/April), and then lastly again in July/August of this next year. 

And, here’s how to apply for compartment exams CBSE .

Learners are thus expected to clear the compartments within these attempts only.

And if you still think that you might have to repeat the whole year, then it’s not worth your overthinking.  

Unless you have failed all subjects or want to improve your marks in each and every 5 subjects, you won’t be considered to rewrite your 12th boards again.

If I Failed In One Subject In 12th CBSE: Immediate Steps to Take After Failing

It can be really daunting if you fail in even one subject

Your own people might start judging you and your whole performance based on these marks, but you shouldn’t lose your calm.

Here are some immediate steps you can take after failing to save yourself from deterioration of mental health.

1. First 24 Hours: Managing Your Emotions

The first day hours after failing one subject in CBSE Class 12 can be challenging to emotional maintenance. Follow the following steps for keeping your coomposure.

  • First thing first, make it clear in your head that one failed subject cannot assess your worth completely.
  • You might experience shame, guilt, embarrassment, or even fear of getting scolded or criticised. Accept them all calmly and positively.
  • Comparison with others, like your friends, relative’s kids, or any other mate from your neighbour can make it worse, so refrain from that.
  • You can have positive self talk, journalling, or confide in a trusted friend to process your feelings. This would lighten your emotional baggage.
  • You can also find your parents or teachers who think well of you, and try seeking assistance from them.
  • In the emotional vagueness you might get impulsive into taking decisions you might regret later. These can be dropping the whole year or not trying again. Avoid such things.
  • Pause, assess, reflect, and regulate your emotions healthily for gaining mental clarity on your next best step.

Learn about emotional intelligence and self-regulation for getting better results of emotional regulation.

2. Week One: Understanding Your Options

Once you are in your clear head, look ahead and plan your actions that truly align with your career aspirations. You can look for the following options.

  • Compartment Exams: The first and foremost option can be to take compartment exams in the same year as result declaration. Once you pass the one failed subject with optimum marks, your marksheet just shows pass without showing any compartment.
  • NIOS: NIOS is another flexible option for students who want to explore work culture while also getting their class 12th passing certificate . You won’t have to lose your academic year for this. But, there can be certain universities which won’t prefer NIOS over CBSE.
  • Distance Learning: Institutes like Swayam, IGNOU, and many private universities provide certifications in distance learning , this honing your other professional skills. These are also accepted by multiple firms for hiring, similar to NIOS.
  • Skill-based Jobs or Entrepreneurship: Having your own small business, or skills like content writing, content creation, digital marketing, freelancing, or event management can open doors of self-employment opportunities.
  • Career-oriented Certificates: Refining your skills from Coursera, Swayam, or NITI Aayog can offer short-term certificates that make your CV chosen by organizations.
  • Diploma or Vocational Courses: Many other diploma courses in engineering, fashion designing, ITs, or graphic designing can give stability to job choices. Universities including ITIs and polytechnics accept such qualifications.
  • Private University Admissions: Private Universities have their own admission criteria and tests after students can continue their education.

Now, you can choose among these options while making a 7 day action plan: 

  • Day 1: See your marksheet and know the area where you dropped marks. It can be the objective MCQs, long answers, short answers, or practicals.
  • Day 2: Have your subject teacher by your side to tell you honestly, where and why you lagged.
  • Day 3: Obtaining the new set of compartment/exam rules by the CBSE is possible through the official CBSE site.
  • Day 4: Choose either re-evaluation, verification or to directly prepare to take the compartment exam.
  • Day 5: Make a 30-45 days study plan, with most attention on areas of weaknesses.
  • Day 6: Solve old 5 year question papers of that subject.
  • Day 7: Tell your parents about your plan and make your final effort in July.

3. Informing Parents and Key Stakeholders

The most crucial yet frightening can be to let your parents and teachers know of your results, so you can:

  • Be your authentic self while sharing your marks with your well-wishers (parents and teachers).
  • Add the fact that you already have a recovery plan (7-day framework).
  • Get them to hear the contents of the compartment option in CBSE, which is not a failure.
  • Seek their assistance rather than their criticism.
  • Communication with key stakeholders such as teachers, and academic counsellors from would-be college admissions is also necessary.
  • They should be reassured that you will not show it in the wrong light.

Common Subjects Where Students Fail and How to Tackle Them

There are some really common subjects in which learners from class 12 fail. Among these are:

  • Physics: Reduce complicated derivations to simple ones. Try to put great emphasis on numerical practice.
  • Chemistry: Know reaction mechanisms, update inorganic, organic concepts, and memorize significant exceptions.
  • Mathematics: Attentive push on the revision of the formulas, NCERT exercises, and study of no less than 20 sample questions a day.
  • Accountancy: Daily practice ledger entries which are conceptualised and not memorised in your mind.
  • Economics: Recurring diagrams, definitions, present implications, and case questions.
  • English Core: You should develop exclusively in writing formats, and resolve comprehension on a regular basis.

Options After I Failed In One Subject In 12th CBSE

The under-mentioned are the best for passing 12th class from CBSE if you fail only one subject.

1. Sit for The Compartment Exam 

This is the most feasible and prevalent option as it is conducted in July every year.

The syllabus remains the same as the board exams, so there won’t be any more added worries for the student.

Although the success rate for compartment exams are severely low ranging from 29%-38%, and you would need strong preparation.

A single subject has to be reattempted and you would get a regular certificate of passing once you pass.

Colleges will accept compartment marks(when cleared in July) except for those which have crossed their deadlines for application earlier.

2. Improvement Exam 

This is for the ones who are less satisfied with their boards marks. 

With improvement exams, the pass subjects having less marks can be upgraded to best potential marks.

This is not necessary in case you have failed one of the subjects

You just work on clearing the compartments first.

3. Re-Evaluation or Verification of Marks

If you believe that the remark of unfair means (UFM) is wrong, or your grades appear too low, or even when you feel there could be an evaluation bias.

You can apply for re-checking (totals) of marks, photocopy of answer sheets, and rediscussion of particular questions.

This comes in handy when you have failed by 2-5 marks.

4. Repeat the Year

You can repeat Class 12 only if there is something with your subject combination and you want to restructure it.

Your desire for an utter new beginning can also lead to repeating the year for class 12th CBSE.

When you miss every effort of the compartment (very rare), you can choose a repeating year.

CBSE Compartment Exam Eligibility Criteria 2025

To be able to be examined in the compartment, you need to:

  • You have just failed in one subject in CBSE Class 12 board exam.
  • You come out as an ordinary/personal candidate.
  • You have not been stamped under UFM (unfair means).

You should apply for the compartment exam either in school (when it is regular) or through the internet (when it is private).

CBSE permits no more than 3 attempts of compartment during a year, so prepare smartly.

Also, the rate of passing compartments is severely low due to tough papers. This would need your serious efforts.

Common Reasons for Failing One Subject (And How to Avoid Repeating Them)
