Who Is Eligible for the Class 12 Compartment Exam 2026?
CBSE recognises three distinct candidate categories for the July 2026 supplementary, and the application process branches accordingly:
Category A: 2026 Compartment Candidates
If your 2026 marksheet (downloaded from cbseresults.nic.in or DigiLocker) shows Compartment against one subject, you must clear that subject in the July exam to be declared Pass. You appear in the same subject in which compartment was placed; the rest of your marks carry forward unchanged.
Category B: Single-Subject Improvement Seekers (Pass Candidates)
If you cleared the 2026 main exam but want to improve in one subject, you can sit the supplementary in that subject. The higher of the two scores is reflected on the revised marksheet, the marksheet itself notes that the score is the improved one. Most cut-off based admissions accept this without prejudice.
Category C: 2025 Compartment Carry-Overs (Final Attempt)
CBSE allows a maximum of three attempts at the compartment subject (the main exam itself counts as the first). If you were placed in compartment in 2025, attempted but did not clear the 2025 supplementary, and re-attempted in 2026 without success, July 2026 is your final permitted attempt. Use it.

Step-By-Step LOC Submission Process
For Regular School Candidates
- 2 June 2026: Inform your school exam coordinator that you intend to appear in compartment / improvement. Schools cannot submit LOC without your written intent.
- The school logs into the CBSE LOC portal using its affiliation credentials, opens Compartment / Improvement LOC 2026, and selects your roll number from the auto-populated 2026 candidate list.
- The school enters subject code(s) you want to reappear in. Cross-check this on a printout, an incorrect subject code is the single most common cause of barred entry on exam day.
- The school remits fees via the CBSE online payment gateway: Rs 300 per theory + Rs 150 per practical (Indian centres). Practical fees apply only if your subject has a practical component (e.g. Physics, Chemistry, Biology, Computer Science, Physical Education).
- The school prints the submitted LOC form for your records. Demand a copy; without it, you have no proof if the submission misfires.
- Admit cards are released approximately 7 to 10 days before the exam on the CBSE Pariksha Sangam portal.
For Private / Patrachar Candidates
- Open the CBSE private candidate portal directly (no school routing). Log in using the credentials issued in your 2026 main-exam admit card cycle.
- Choose Class XII Compartment / Improvement 2026, enter subject codes, upload a recent photograph and signature if prompted.
- Pay online via the same CBSE gateway. Private candidates do not have school-borne administrative fees, but the per-subject CBSE charge is identical.
- Download the LOC acknowledgement. Save the PDF to DigiLocker for retrieval on exam day.
Document Checklist Before You Sit on 15 July
- CBSE admit card (download from Pariksha Sangam approximately 7 days before)
- Original photo ID, Aadhaar or PAN, that matches the admit card details
- 2026 main-exam marksheet (digital from DigiLocker is acceptable, see our DigiLocker download guide)
- Transparent geometry box, blue/black ballpoint pen (CBSE prohibits gel pens for some subjects, check the admit card instructions)
- A clear water bottle, no labels
- For PCM/PCB candidates: scientific calculator only if your subject permits, check the admit card list
The 60-Day Prep Sprint: 15 May to 15 July
You have roughly nine weeks. The prep mix differs sharply by category:
Category A (Compartment)
Treat this as a fresh deep-dive into a single subject. The detailed week-by-week sprint plan is in CBSE Class 12 Supplementary Exam 2026: 60-Day Prep Plan. The TL;DR: weeks 1 to 2 syllabus revision; weeks 3 to 6 chapter-wise problem sets; weeks 7 to 8 full-length papers; week 9 controlled revision.
Category B (Improvement)
You already cleared the subject, so the goal is jumping bands, e.g., from 72 to 85+. Focus on previous-year papers from 2022 to 2026 main and supplementary, plus marking-scheme-aligned answer writing.
Category C (Final attempt)
This is psychological as much as academic. Get a mentor or counsellor on the phone weekly. Free counselling is available on 7033005444.
What Happens After 15 July 2026?
- Result: Typically declared in the first week of August 2026. Mode: same DigiLocker + UMANG push as main exam.
- Pass / Fail: Pass candidates get a fresh DigiLocker marksheet superseding the May version. Failed candidates may apply for the 2026 supplementary’s own photocopy/revaluation cycle.
- College admissions: Most counselling rounds (DU CSAS, JoSAA, NEET counselling) accept compartment-cleared marksheets if produced before the document verification deadline of the respective counselling round. Cross-reference our DU CSAS 2026 Application Calendar for hard deadlines.
Pivoting to a Competitive Exam in Parallel
If you are already preparing for an entrance, the compartment is a brief detour, not a derailment:
- Engineering: Continue JEE prep on a 60/40 split (60% compartment subject, 40% JEE). Our cross-site guide on JEE Gurukul walks through a drop-year programme that absorbs the compartment month.
- Medical: NEET UG counselling typically begins late July, document deadlines are tight. NEET Gurukul documents the seat-allotment cycle for late-document candidates.
- Commerce / Arts / Law: CUET UG result is due in June-July; on the law side, see CUET Gurukul for B.A. LL.B. options and the broader Class 12 to JEE/NEET/CLAT 2027 Transition Roadmap.
Fee Snapshot, India vs Outside India
| Item | India | Abroad (indicative) |
|---|---|---|
| Theory subject (per paper) | Rs 300 | Rs 2,000+ |
| Practical subject (per paper) | Rs 150 | As per CBSE Gulf/SAARC schedule |
| Late fee (post LOC deadline) | Rs 2,000 (typical) | Variable by region |
Exact 2026 fees may vary slightly, confirm on the CBSE LOC portal once the window opens 2 June 2026.
Common Mistakes That Cost the Year
- Missing the LOC window: Schools often consolidate LOCs in the last 48 hours. Do not assume your name auto-rolls over; submit written intent by 5 June at the latest.
- Wrong subject code: Especially common for English Core (301) vs English Elective (001), or Hindi Core/Elective. Verify on a printout.
- Forgetting it counts as an attempt: If you appear and skip, the attempt is still counted. Show up and write.
- Not downloading the admit card on time: The Pariksha Sangam portal lags closer to the exam date. Download the moment it is released.
- Ignoring counselling document deadlines: The supplementary marksheet usually arrives early August. If your target college’s last verification date is 5 August, you have zero buffer.
