Core ConceptRead this first — the foundation of the topic
TOPIC CHECK
All sentences should discuss the SAME main idea. If one sentence jumps to a different topic, it's odd.
2
COHERENCE
Sentences should flow together like a story. They should have a logical connection—cause-effect, example-explanation, or continuous thought.
3. TIME & TENSE: Check if all sentences use consistent time references. If three talk about past and one about future without reason, the odd one stands out.
4.
PERSON & PERSPECTIVE: If three sentences use 'he/she/they' and one uses 'I/me,' it may be odd (unless there's a reason).
5. STYLE & TONE: Academic formal writing mixed with casual slang in one sentence makes it odd.
6
SUPPORTING DETAILS
Some sentences support a main idea, one may be random or unrelated information.
Exam PatternsWhat examiners ask — read before attempting PYQs
IN SSC CGL:
- Usually 4 sentences given; choose the odd one (A, B, C, or D).
- Often tests logical sequence and paragraph coherence.
- Questions appear in reading comprehension or standalone para-jumbling sections.
SHORTCUT/TRICK:
"Read the first three sentences and build a mental paragraph. Then check sentence 4 against this frame. If it doesn't fit, it's odd." This is faster than analysing each sentence individually.

60-Second Revision — Odd Sentence Out
Remember: ODD = breaks TOPIC, FLOW, or LOGIC. Not about grammar—about coherence.
Trick: Read sentences 1-3, build the paragraph theme, then check sentence 4 against this mental frame.
Watch for: Sudden topic jumps (agriculture → politics), tense shifts, or changed person (they → I).
Formula: If 3 sentences form a connected idea and 1 stands alone, that 1 is odd.
Trap: Don't confuse 'good writing' with 'fitting in.' A well-written sentence can still be the odd one.
Test yourself: In 30 seconds, identify the main idea of the paragraph. The sentence NOT supporting it = the answer.
