Is the CDS Exam Really Hard? Preparation Tips & Insights
Table of Contents

When people think about joining the Indian Armed Forces through the CDS exam, the first question that comes to mind is usually – is CDS exam tough? Honestly, it’s different for everyone. Some find it manageable, while others feel it’s really challenging. The difficulty often depends on how you prepare, your basics in subjects like English, Maths, and General Knowledge, and how you handle competition. In this guide, we’ll break down what makes the CDS exam tough and share tips to make your preparation easier.
What is the CDS Exam and Who Can Apply?
Before debating whether the exam is tough or not, it’s good to know what it actually is. The CDS exam, conducted by the Union Public Service Commission (UPSC), recruits’ candidates for the Indian Military Academy (IMA), Indian Naval Academy (INA), Air Force Academy (AFA), and Officers Training Academy (OTA).
Eligibility is fairly straightforward – you need to be a graduate, within a specific age bracket, and physically fit. Sounds simple, right? But the simplicity of eligibility is where the real challenge hides. Because this broad gate allows lakhs of candidates to apply, and the competition shoots through the roof.
Is the CDS Exam Tough or Just Overhyped?
A lot of aspirants keep asking – is CDS exam tough compared to other defence tests? The truth is, the paper itself isn’t rocket science, but the catch is in the volume of competition and the unpredictability of questions. Unlike exams where the syllabus is highly focused, CDS requires a mix of English, General Knowledge, and Mathematics – and that blend makes it tricky.
Some students with strong basics may call it easy, while others drown in the vastness of GK or the time pressure of maths. So it’s tough for some, moderate for others, but definitely not a cakewalk for anyone.
Which Part of the CDS Exam is the Hardest?
Let’s get real, not all sections are equal in difficulty.
- English Section: It looks simple on paper, but the comprehension passages, error detection, and vocabulary can sometimes be unexpectedly tricky. If you’re not in the habit of reading, English may feel like a roadblock.
- General Knowledge: Without doubt the most unpredictable. Questions can range from history, polity, economics, current affairs, geography to science – literally everything under the sun. Many aspirants agree this is where most marks are lost.
- Mathematics: The level is around high school (class 10), so not very advanced. But solving quickly under time pressure, with negative marking looming, makes it harder than it looks.
So if someone asks you is CDS exam tough subject-wise, you could confidently say GK is the most confusing, English is tricky, and Maths is manageable if your basics are sharp.
How Competitive is the CDS Exam?
Even if you’re well-prepared, the number of competitors makes CDS feel tougher. Every year lakhs apply, but only a small percentage finally make it to the academies. Cut-offs fluctuate depending on the paper’s difficulty and the number of vacancies, but they’re never too low.
This means it’s not only about clearing minimum marks but also performing well above average. The competition is like a marathon where everyone is sprinting, and if you stop for a breather, others will overtake you.
How Much Time Should You Spend Preparing for CDS?
A common worry: “How many months are enough?” The answer isn’t universal. For someone with a strong base in English and Maths, 3–4 months of consistent preparation could be enough. But if GK is your weak area, even a year might feel short.
The exam tests consistency more than anything else. Studying in bursts of motivation and then leaving gaps will make you feel like CDS is harder than it really is. Better to study steadily every day, even if just 2–3 hours, than cramming endlessly in the last month.
Why Do Aspirants Find the CDS Exam Tough?
There are multiple reasons.
- The breadth of GK makes students nervous.
- Negative marking means even one careless guess can sink your score.
- Balancing studies with graduation or job responsibilities often feels overwhelming.
- Many underestimate English and later regret it.
- So, when people say is CDS exam tough, often it’s not just the paper but the circumstances around preparation that make it challenging.
Is CDS Harder Than NDA or AFCAT?
A popular comparison. NDA is for 12th pass students, while CDS is for graduates, so naturally, the level of questions is a bit higher. AFCAT, on the other hand, is considered slightly easier than CDS, but its selection ratio is still competitive.
In terms of toughness, most agree: NDA < AFCAT < CDS. However, the final verdict depends on your strengths. Someone strong in English may find CDS easier than NDA maths, while a science student may enjoy AFCAT more.
Can a Beginner Crack CDS in the First Attempt?
Absolutely. First-attempt success stories are common. It requires discipline and the ability to learn from past years’ papers. But don’t assume it’s easy. You’ll need to follow a strategy, stay regular, and avoid the temptation of only reading current affairs without touching core GK topics.
If you’re consistent, even as a beginner, you won’t need years. But inconsistency will make you join the long list of “next attempt hopefuls.”
Tips to Make CDS Exam Preparation Easier
Some ideas that work well:
- Solve Previous Year Papers: This gives a real sense of difficulty level.
- Focus on GK Gradually: Read newspapers, yearbooks, and revise NCERT basics.
- Time Management: Practice with a timer to handle the exam pressure.
- English Improvement: Read editorials, learn idioms, practice comprehension daily.
- Maths Strategy: Stick to basics but practice speed and accuracy.
Small tip – don’t try to master everything. Prioritize and play smart.
Should You Join Coaching for CDS?
Coaching isn’t mandatory, but it helps. If you’re disciplined and can follow a study plan, self-study works perfectly fine. However, many aspirants feel coaching gives them a structure, accountability, and exposure to mock tests.
If you’re someone who struggles to stay consistent, a good coaching institute can definitely make CDS feel less tough. But don’t depend solely on coaching – self-effort is the biggest factor.
