Normal practice, or a Simulated test
Both use the same questions. Normal practice is untimed and needs no account: choose an option and the answer and solution appear at once. The Simulated test is the real computer-based format, with one 15-minute clock, a question palette and full screen, and your score, the key and the solutions arrive when you submit.
How the two modes differ
No account needed
Normal
UntimedEvery question on one page, loading as you scroll. Choose an option and see straight away whether it was right.
- No timer. Nothing to start and nothing to submit. Stop whenever you like.
- Answered as you choose. Tap an option and it is marked at once, with the correct answer shown.
- Solutions in place. The explanation, and the video where one has been added, sit under the question.
- Open to guests. Normal practice needs no sign-in.
Real exam conditions
Simulated
Timed CBTThe computer-based test format: one clock, a question palette, and a score the moment you submit.
- A clock that does not pause. 15 minutes from the moment you begin, and the paper is submitted for you when it reaches zero.
- Question palette. Answered, not answered and marked for review, section by section, as the real interface has it.
- Full screen, proctored. The test takes over the screen; leaving it three times submits the paper.
- Answers hidden until you submit. The key, the explanations and your score all arrive together at the end.
About this test
SSC CGL 2025 Tier 1 Reasoning PYQ 16 Sep Shift 3: What It Covers
Use this set to test how quickly you crack the coding, series and symbol-based questions SSC actually set. It is the General Intelligence and Reasoning section of the SSC CGL 2025 Tier 1 exam held on 16 September 2025, Shift 3. On Aptitude360, most questions come with written solutions.
Reasoning topics in the 16 Sep Shift 3 section
- Letter series and number series built on powers and differences
- Coding-decoding with letter shifts and letter-to-digit codes
- Mathematical operations using substituted signs and custom symbols
- Blood relations, including relations written as coded symbols
- Inequality-based conclusions, statement and conclusion, and assumptions
- Alphabet-position analogies, word formation, address matching and odd one out
Key rules for series and coding questions
- nth term of a GP: \( T_{n}=ar^{n-1} \)
- Common ratio from two terms: \( r^{m-n}=\dfrac{T_{m}}{T_{n}} \)
- Common difference of an AP: \( d=T_{n+1}-T_{n} \)
- Opposite letter position: \( 27-n \)
How to prepare for CGL reasoning of this kind
- Write alphabet positions and their reverse values on rough paper before solving letter analogies
- For digit-code questions, match letters common to two given words first
- In inequality chains, link the two terms only through signs pointing the same way
- Replace all swapped symbols before applying BODMAS
Who this reasoning set suits
SSC CGL aspirants who want section-specific practice on actual Tier 1 reasoning questions, especially after revising coding, series and blood relations, will find it useful.
