Section-wise breakdown
The paper ran five subjects of 40 marks each, in this order. The "available here" column is read from our question bank as this page loads, so it is what the test will actually give you today.
| Section | Question numbers | In the paper | Available here |
|---|---|---|---|
| Mental Ability | 1–40 | 40 | 40 |
| General Awareness | 41–80 | 40 | 40 |
| Arithmetic Ability | 81–120 | 40 | 40 |
| General English | 121–160 | 40 | 20 (in progress) |
| General Hindi | 161–200 | 40 | 40 |
| Total | 1–200 | 200 | 180 |
The gaps are real: question and option text in DSSSB's file are images, not text, so each remaining question has to be transcribed by hand and checked against the tick in the key. We would rather show 180 verified questions than 200 padded ones.

कार्बन मोनोऑक्साइड (CO) की हीमोग्लोबिन के लिए ऑक्सीजन की तुलना में बहुत अधिक आकर्षण होती है, जिससे कार्बोक्सीहीमोग्लोबिन बनता है जो ऑक्सीजन परिवहन को रोकता है। - Carbon monoxide
- Arithmetical & Numerical AbilityThe average of 25 results is 18. The average of first twelve of them is 14 and that of the last twelve is 17. The thirteenth result is:
25 परिणामों का औसत 18 है। उनमें से पहले बारह का औसत 14 है और अंतिम बारह का औसत 17 है। तेरहवां परिणाम है:- 72
- 75
- 78
- 81
Show answer and solution
Answer: (C) 78
Sum of 25 results = 25 * 18 = 450.
Sum of first 12 = 12 * 14 = 168.
Sum of last 12 = 12 * 17 = 204.
13th result = 450 - (168 + 204) = 450 - 372 = 78.
13वां परिणाम = 450 - 372 = 78. - English Language & ComprehensionFill in the blanks with the most appropriate word.

Frequently asked questions
How many questions from the 2019 Shift 1 paper are on this page?
This test has 180 of the 200 questions from the 16 July 2019 Shift 1 paper. These sections are still incomplete: General English (20 of 40). We publish the real count rather than padding the paper with questions DSSSB did not ask.
Is the answer key the official one?
Yes. Every correct option is the one DSSSB ticked in its own answer-key PDF for this shift. The worked solutions underneath are written for this site and are not part of the official key.
Do I need to log in to take the test?
No. The test starts without an account. Creating one only saves your result so you can compare attempts later.
What is the marking scheme?
The same as the real paper: 1 mark for a correct answer, 0.25 deducted for a wrong one, nothing for a question you leave blank. The timer is set to the official 120 minutes.
Why does my option number differ from the PDF?
DSSSB switched on option shuffling for this exam, so the order on a candidate's screen was not the order in the PDF. Match your answer by the option text, not its number.
