December Exam Rush: 3 Defence Papers in 15 Days

Last verified: 6 October 2026. RIMCEE dates (6 December exam, 9–11 October correction window) are ✅ CONFIRMED from the NTA schedule reported by Jagran Josh; RMS CET details (13 December exam, 20 October application deadline) are ✅ CONFIRMED from the official notification reported by NDTV; the UP Sainik School exam date of 20 December is 🔶 EXPECTED (tentative, per the official society website). AISSEE 2027 on 31 January is the tentative date from NTA’s exam calendar.

December is not just a month anymore for defence-school aspirants — it is a gauntlet. Three separate entrance exams land within fifteen days of each other: RIMCEE on 6 December, RMS CET on 13 December, and the UP Sainik School exam on 20 December. And just to keep the year-end interesting, the JNVST Class 6 paper sits a week before all of them, on 28 November. If your child is appearing in more than one, this is the month that decides their year.

The December calendar, at a glance

The sharpest point first: only one of these four still accepts applications — RMS CET. The RIMCEE window is already shut (late-fee route closes tomorrow, 7 October at 11:50 pm), JNVST forms are done, and the UP Sainik School regular-fee window closes on 25 October. If RMS CET is on your child’s list, there is no later chance — apply before 20 October to avoid the Rs 500 late fee.

Why these three get mixed up — and why they shouldn’t

Parents often treat these as interchangeable “military school exams.” They are not. RIMCEE is the gateway to a single institution — the Rashtriya Indian Military College, Dehradun — and it is a two-stage process: a written exam in English, Mathematics and General Knowledge, then a viva-voce for those who clear it (tentatively April 2027). RMS CET is a single pen-and-paper MCQ test for five schools across four states — Chail, Ajmer, Dholpur, Belgaum and Bengaluru. The UP Sainik School exam is the outlier: one 200-mark OMR paper in 2 hours 30 minutes, run by the UP Sainik Schools Society, with strict domicile rules that quietly disqualify families every year.

The preparation overlap is real — mathematics, English and general knowledge are common ground — but the pace of the papers is very different. A child sitting the UP paper on 20 December a week after RMS CET needs to mentally switch gears, not just subjects.

What to do this week

1. RMS CET is the last open door. If your child hasn’t applied, file before 20 October (5 pm) at exams.nta.nic.in/rmscet. After that, only the 21–25 October late-fee route remains.
2. RIMCEE candidates: use the correction window. It runs 9–11 October — three days to fix a wrong date of birth, blurred photograph, or a swapped category. After that, no edits.
3. UP Sainik School forms: don’t wait for 25 October. The father-child domicile rule is the silent killer of applications — both must hold a UP domicile certificate.
4. Map the gaps between papers. There are 7 days between RIMCEE and RMS CET, and 7 more to the UP exam. Plan full-length mock papers in each exam’s exact format, not generic practice.

We’ve been tracking each of these closely: our RIMCEE pattern explainer breaks down how the 6 December paper differs from AISSEE, the UP Sainik School deadline guide covers the 200-mark paper and domicile rules, and our RMS CET deadline piece has the fee and eligibility details. For the youngest aspirants, there’s the JNVST Class 6 countdown.
