in, on, at, by, for, with, from, to, under, over, between, among, through, during, since, until
💡KEY RULES FOR TIME PREPOSITIONS
• AT - specific times (at 5 PM, at noon, at night)
• ON - days and dates (on Monday, on 15th August)
• IN - months, years, seasons (in January, in 2023, in summer)
• SINCE - starting point (since morning)
• FOR - duration (for 2 hours)
• BY - deadline (by evening)
• DURING - throughout a period (during the match)
KEY RULES FOR PLACE PREPOSITIONS:
• AT - specific points (at home, at the station)
• ON - surfaces (on the table, on the road)
• IN - enclosed spaces (in the room, in Delhi)
• ABOVE/OVER - higher position
• BELOW/UNDER - lower position
• BETWEEN - two things (between you and me)
• AMONG - more than two (among friends)

Formula Block
Memorise — at least one formula appears in every paper
Time Formula: AT (specific) → ON (days) → IN (periods)
Place Formula: AT (point) → ON (surface) → IN (space)
Movement Formula: TO (destination) / FROM (source) / THROUGH (passage)

Exam Patterns
What examiners ask — read before attempting PYQs
📋SSC CGL typically tests prepositions through
1
First blank needs specific time → use AT
2
Second blank needs specific day → use ON
Answer: 'The meeting is scheduled AT 3 PM ON Monday.'
WORKED EXAMPLE 2:
Question: 'He has been working ___ the company ___ 5 years.'
1
First blank shows association → use FOR or IN or WITH
2
'working in the company' is correct (enclosed workspace)
3
Second blank shows duration → use FOR
Answer: 'He has been working IN the company FOR 5 years.'
SHORTCUT 2 - FIXED PREPOSITION PAIRS:
• Different FROM (not 'different than')
• Consist OF (not 'consist in')
• Comply WITH (not 'comply to')
• Capable OF (not 'capable to')
SHORTCUT 3 - MOVEMENT PREPOSITIONS:
• INTO = movement inside (walked into the room)
• ONTO = movement on surface (climbed onto the roof)
• Use TO for destination, FROM for source
COMMON MISTAKE #1 - THE BIGGEST TRAP:
Students confuse IN and AT for places
💡Remember
Use IN for cities/countries (in Mumbai, in India) but AT for specific locations (at the airport, at school). This confusion appears in 60% of preposition questions
⚠️OTHER COMMON ERRORS
• Writing 'on time' vs 'in time' - 'on time' means punctual, 'in time' means before deadline
• Using 'from' instead of 'since' for time - use SINCE for point of time, FROM for place
• Mixing up 'between' and 'among' - use BETWEEN for two items, AMONG for more than two
The key to mastering prepositions is practice and memorizing fixed combinations. Many prepositions don't follow logical rules - they must be learned through repetition.
