The SSC GD Constable exam pattern explained

Every year, lakhs of young people apply for the SSC GD Constable exam. For many of them it is the first real chance at a permanent government job in uniform. You only need to have passed Class 10. The posts are constables in the Central Armed Police Forces and related organisations: the forces that guard India's borders, protect airports and industries, and keep order during elections and emergencies.

This exam is different from most SSC exams in one big way. It tests your body as well as your mind. A good score in the written paper means nothing if you cannot finish the run in time. So before you open a single book, understand the whole route.

The four stages

Only one stage decides your rank: the CBE. Every other stage is a gate. You either pass it or you are out, however high your written score.

The computer-based exam

• Time: 60 minutes for the whole paper. There is no separate time limit for each section, so you can move between sections freely (as reported).
• Marking: 2 marks for each correct answer. 0.25 is deducted for each wrong answer. An unattempted question gets zero.
• Language of the paper: English, Hindi and 13 regional languages. The language section itself is English or Hindi; you choose one.
• Many shifts: the exam runs over many days and shifts, so SSC normalises scores across shifts. The notification explains the method.

How your score is worked out

Suppose a candidate attempts 64 questions. 56 are right and 8 are wrong.

1. Marks for right answers: 56 × 2 = 112.
2. Deduction for wrong answers: 8 × 0.25 = 2.
3. Raw score: 112 − 2 = 110 out of 160.

Notice how small the penalty is. Eight wrong answers cost only 2 marks, the same as one right answer.

Should you guess?

Each question has four options. A right answer earns 2 marks and a wrong one costs 0.25, so a wrong answer costs only one-eighth of what a right answer earns.

• If you can rule out two options, you are choosing between two. On average a guess then gains (½ × 2) − (½ × 0.25) = 1 − 0.125 = 0.875 marks. That is clearly worth it.
• Even a blind guess gains a little on average: (¼ × 2) − (¾ × 0.25) = 0.5 − 0.1875 = 0.3125 marks.

So the maths favours an educated guess. What it does not favour is rushing. Careless mistakes on questions you actually know are the real loss.

Qualifying marks

To be called for the physical tests you need a minimum score in the CBE. Recent notifications have set it at:

The physical tests

Height is relaxed for Scheduled Tribe candidates and for candidates from certain hill areas and North-Eastern states. Weight must be in proportion to height and age. For the full tables, see our guide to PET and PST standards.

For men, the 5 km run is the hardest part of the PET. It needs an average pace of 4 minutes 48 seconds per kilometre or faster (24 ÷ 5 = 4.8 minutes). That is not something you can build in the four weeks after your result. Start running now.

Medical examination and documents

The medical examination checks eyesight, general health and fitness for field duty. Problems such as knock knees, flat feet or poor vision can lead to rejection, so a check-up early in your preparation is sensible.

At document verification you show original certificates: Class 10, caste or category, domicile, NCC (if you claim a bonus) and others the notification lists. A missing or wrongly issued certificate can cost you a post you earned. Our eligibility guide has a checklist.

How merit is made

• Merit is prepared state-wise (vacancies are allotted by state and, in some cases, by border or special areas) and category-wise.
• It is based on CBE marks (normalised), plus NCC bonus marks where applicable.
• You must pass the PET, PST, medical examination and document checks to stay in the list.
• Your force depends on your merit, your state's vacancies and your preferences.

What the pattern means for your preparation

1. Treat all four sections equally. Each carries 40 marks. There is no "extra" section to make up for a weak one.
2. Plan your 60 minutes. You get 45 seconds per question on average (60 × 60 = 3,600 seconds ÷ 80 = 45).
3. Run from day one. Written marks rank you, but the run can end your chances.
4. Know your state. Merit is state-wise, so the competition in your state matters more than national numbers.
5. Get your documents in order now, not after the result.

A simple way to split the 60 minutes, which you can adjust after a few mocks:

For what to study in each section, read the SSC GD syllabus, analysed.

Practice

1. How many questions does the CBE have, and how long do you get?
2. A candidate gets 50 right and 12 wrong. What is the raw score?
3. What is the minimum qualifying score, in marks, for an unreserved candidate?
4. Are the physical tests scored or qualifying?
5. Is merit prepared nationally or state-wise?

Answers:

1. 80 questions in 60 minutes.
2. 50 × 2 = 100; 12 × 0.25 = 3; 100 − 3 = 97.
3. 30% of 160 = 48 marks (as reported).
4. Qualifying. They do not add marks.
5. State-wise, and category-wise within each state.

Your next steps

• Download the latest notification from ssc.gov.in and read the scheme of examination.
• Take one full 80-question mock this week, just to see where you stand.
• Time a 1.6 km run (women) or a 5 km run (men) to know your starting point.
• List every document you will need and check that each one is in your correct name.
