An SSC CHSL marks calculator adds 2 marks for every correct Tier 1 answer and cuts 0.5 for every incorrect one, so 70 correct and 19 incorrect come to 130.5 out of 200. Blank questions score zero either way. Tier 2 is stricter: 3 marks per correct answer and a full mark lost per incorrect one.
CHSL recruits for posts such as Lower Division Clerk, Junior Secretariat Assistant and Data Entry Operator. Its Tier 1 paper has exactly the CGL Tier 1 layout, while Tier 2 is a shorter paper. Further down you will also find the scoring rule for SSC MTS, which many CHSL aspirants take as well. Your final, normalised marks always come from the Commission.

SSC CHSL notice on ssc.gov.in
CHSL Tier 1 = 2 x correct - 0.5 x incorrect (max 200)
Correct means your option matches the answer key. Incorrect means you marked an option that does not match. Unmarked questions are left out.
What to type in the SSC CHSL marks calculator
The tool above is set up for Tier 1. It shows four parts in the order English, General Intelligence, Quantitative Aptitude and General Awareness, with 25 questions in each. Put the number of correct and incorrect answers against each part. The panel then gives you the marks of each part and a grand total out of 200.
You will find both counts in the response sheet that SSC opens along with the tentative key. It marks your chosen option next to the right one for every question. Many students tick the matches on a printout before typing anything, which avoids a miscount.
- Log in to the SSC portal and open the CHSL response sheet with the answer key.
- Go part by part: English, General Intelligence, Quantitative Aptitude, General Awareness.
- Note the correct and incorrect counts of each part.
- Enter them in the calculator above and read the total out of 200.
- For Tier 2, multiply correct answers by 3 and subtract the incorrect count.
Tier 1 pattern in one table
| Part | Questions | Marks | Penalty per error |
|---|---|---|---|
| English Language | 25 | 50 | 0.5 |
| General Intelligence | 25 | 50 | 0.5 |
| Quantitative Aptitude | 25 | 50 | 0.5 |
| General Awareness | 25 | 50 | 0.5 |
| Whole paper | 100 | 200 |
The hour is split into four locked blocks of 15 minutes. When the timer for one part runs out, the screen moves on, so you cannot go back to finish a reasoning puzzle later.
A full Tier 1 example
English: 22 correct, 2 incorrect. 44 - 1 = 43
General Intelligence: 20 correct, 4 incorrect. 40 - 2 = 38
Quantitative Aptitude: 16 correct, 5 incorrect. 32 - 2.5 = 29.5
General Awareness: 12 correct, 8 incorrect. 24 - 4 = 20
Grand total: 43 + 38 + 29.5 + 20 = 130.5 out of 200. A quick cross check: 70 correct give 140, and 19 incorrect take away 9.5, which also leaves 130.5.
Look at General Awareness here: 8 incorrect answers wiped out 4 marks, equal to two correct answers. If you were truly unsure on those, leaving a few blank would have kept the total higher.
SSC CHSL tier 2 marks calculator rules
An ssc chsl mains marks calculator must follow Tier 2, which is a smaller paper than its CGL cousin. Session I has three sections, all with the same 3 mark and minus 1 rule.
| Section | Questions | Max marks | Counts for merit |
|---|---|---|---|
| Section I: Mathematics 30 + Reasoning 30 | 60 | 180 | Yes |
| Section II: English 40 + General Awareness 20 | 60 | 180 | Yes |
| Section III: Computer Knowledge Test | 15 | 45 | Qualifying only |
| Session II: Skill or Typing Test | Qualifying only |
Section I: 45 correct, 8 incorrect. 135 - 8 = 127.
Section II: 40 correct, 12 incorrect. 120 - 12 = 108.
Tier 2 total: 127 + 108 = 235 out of 360.
Computer test: 9 correct, 3 incorrect. 27 - 3 = 24 out of 45.
Note the two differences from CGL: CHSL Section II has 40 English and 20 General Awareness questions (60 in all), and its computer test has 15 questions instead of 20. Use the negative marking calculator to enter these Tier 2 settings.
SSC MTS marks calculator rule
The MTS and Havaldar exam is held in two sessions on the same day, and you must sit both. The scoring of the two sessions is not the same, which trips up many students who use a single formula.
| Session | Subjects | Questions | Marks | Negative |
|---|---|---|---|---|
| Session I (45 min) | Numerical and Mathematical Ability 20, Reasoning 20 | 40 | 120 | None |
| Session II (45 min) | General Awareness 25, English 25 | 50 | 150 | -1 per error |
Session I: 30 correct, 7 incorrect. No penalty, so 30 x 3 = 90 out of 120.
Session II: 32 correct, 10 incorrect. 96 - 10 = 86 out of 150.
How the two sessions feed the merit list is laid down in the SSC MTS notice, so read it before you add them together. A DSSSB MTS marks calculator, an IB MTS marks calculator or a DDA MTS marks calculator needs the scheme of that body, so take the marks per question from those notices.
Normalisation for CHSL and MTS shifts
Both exams run in many shifts. To keep things fair, SSC now uses the equipercentile method. Think of it like this: your rank inside your own shift is worked out first, and you are then given the mark that sits at the same rank on one shared scale. A tough shift pushes scores up a little; an easy one pulls them down.
That is why an ssc mts normalization marks calculator or a CHSL one can only ever guess. The raw score from the tool above is exact for your answer key, and the normalised figure arrives with the result.
Slips to avoid when you check the answer key
| Slip | Reason it fails | Do this instead |
|---|---|---|
| Applying CGL Tier 2 numbers to CHSL | CHSL Section II has 60 questions, CGL has 70 | Use a maximum of 180 for each CHSL section |
| Deducting marks in MTS Session I | Session I has no negative marking | Score Session I as 3 x correct only |
| Adding the computer test to Tier 2 merit | It is qualifying | Merit uses Sections I and II only (360) |
| Counting a bonus question twice | A dropped question is usually credited by SSC | Follow the final key notes |
Questions students ask
How do I calculate CHSL marks from the answer key?
Take the correct and incorrect counts from every Tier 1 part. Multiply correct by 2 and subtract half of the incorrect count. You end up with a score out of 200.
Is the CHSL Tier 1 pattern the same as CGL Tier 1?
Yes. Both have 100 questions in four parts of 25, 2 marks each, minus 0.5 for an error, and 15 minutes per part. The difference lies in Tier 2.
What is the chsl mains marks calculator rule?
Tier 2 gives 3 marks for each correct answer and takes 1 for each incorrect one. Sections I and II carry 180 marks each, which makes 360 the merit maximum.
Does SSC MTS cut marks for incorrect answers?
Only in Session II, where each incorrect answer costs 1 mark. Session I, with Maths and Reasoning, has no negative marking.
Can I use this for the DSSSB or DDA MTS answer key?
Those exams are conducted by other bodies, and their marking may differ. Take the marks per question and the penalty from their notice and enter them in the negative marking calculator.
Why is my normalised CHSL score different from my raw score?
SSC adjusts scores across shifts using the equipercentile method. A harder shift can raise your marks and an easier one can lower them.
