Chandigarh and the surrounding Tricity have a long connection with the armed forces. Many families here have a parent, uncle or grandparent in uniform, and every year thousands of young people from Punjab, Haryana and Himachal sit for NDA, CDS and AFCAT. If you are one of them, the next few months matter, because the 2027 exam cycle is about to begin.
Key Dates for the 2027 Defence Exams
According to the UPSC calendar for 2027, here is how the first half of the year looks:
| Exam | Notification | Last Date to Apply | Written Exam |
| NDA & NA (I) 2027 | 2 December 2026 | 22 December 2026 | 11 April 2027 |
| CDS (I) 2027 | 2 December 2026 | 22 December 2026 | 11 April 2027 |
| NDA & NA (II) 2027 | 12 May 2027 | 1 June 2027 | 19 September 2027 |
| CDS (II) 2027 | 12 May 2027 | 1 June 2027 | 19 September 2027 |
AFCAT is conducted by the Indian Air Force, not UPSC. The AFCAT 1 2027 notification is expected around November–December 2026, with the exam likely in early 2027. Always confirm dates on upsc.gov.in and afcat.edcil.co.in before applying.
That leaves roughly five months between now and the April written exam. That is enough time to prepare well, but only with a plan.
What Makes Defence Exam Preparation Different?
Defence aspirants have to clear two very different hurdles.
- The written exam tests Mathematics, English and General Knowledge. It rewards concept clarity and steady practice.
- The SSB interview tests personality, communication, group behaviour and officer-like qualities over five days. It cannot be crammed.
A good coaching programme prepares you for the first while quietly building the habits needed for the second, such as reading newspapers, speaking in English, and staying physically fit.
What to Look For in a Defence Coaching Institute in Chandigarh?
Strong Mathematics teaching
NDA Mathematics carries 300 marks and covers Class 11 and 12 topics such as trigonometry, calculus, matrices and probability. Look for a teacher who builds concepts from basics and then moves to exam-level questions.
An English faculty who teaches usage, not just rules
English appears in NDA, CDS and AFCAT. Questions on vocabulary, error spotting, sentence improvement and comprehension are common. You need regular practice with feedback.
General Studies with current affairs
History, Geography, Polity, Science and current events form a big part of the General Ability Test in NDA and the GK paper in CDS. Weekly current affairs sessions are a must.
Full-length mock tests in the real format
Each exam has its own negative marking and time pressure. Practising in the exact format before exam day removes surprises.
Basic SSB orientation
Even a few sessions on the interview process, picture perception and group discussion help you start preparing your mindset early.
A Five-Month Plan Until April 2027

Frequently Asked Questions
When is the NDA 1 2027 exam?
As per the UPSC 2027 calendar, the NDA & NA (I) 2027 written exam is scheduled for 11 April 2027, with the notification due on 2 December 2026.
Can girls apply for NDA?
Yes. Since 2021, unmarried women candidates have been eligible to apply for NDA, subject to the same educational and age conditions as men.
Is coaching necessary for the NDA exam?
Not strictly, but structured coaching helps most students cover the large Maths syllabus on time and get regular test practice. It is especially useful if you are also studying for Class 12 board exams.
Which is easier, CDS or AFCAT?
Neither is easy, but they test different strengths. AFCAT has more reasoning and numerical ability questions, while CDS (for IMA, INA and AFA) includes a full Mathematics paper. Read our detailed comparison of CDS and AFCAT to decide.
