Core ConceptRead this first — the foundation of the topic
Common prepositions include
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 BlockMemorise — 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)

- THE 'AIM' METHOD:
A - AT for specific (AT 6 PM, AT Delhi station)
I - IN for general/enclosed (IN morning, IN the box)
M - ON for surface/days (ON table, ON Sunday)

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
Exam TrapsCommon mistakes students make — avoid these
#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.
Key Points to Remember
AT for specific times and points, ON for days and surfaces, IN for periods and enclosed spaces
SINCE shows starting point in time, FOR shows duration of time
BETWEEN is used for two items, AMONG is used for more than two items
Time Formula: AT (specific) → ON (days) → IN (periods)
Place Formula: AT (point) → ON (surface) → IN (space)
Different FROM, Consist OF, Comply WITH, Capable OF are fixed combinations
INTO shows movement inside, ONTO shows movement on surface
ON TIME means punctual, IN TIME means before the deadline
Use IN for cities/countries, AT for specific locations within them
Movement prepositions: TO (destination), FROM (source), THROUGH (passage)
Exam-Specific Tips
Different FROM is correct, never use 'different than' or 'different to'
Consist OF is the only correct form, never 'consist in' or 'consist with'
Comply WITH is correct, never use 'comply to' or 'comply of'
Capable OF doing something is correct, never 'capable to do'
Preposition questions appear 5-7 times per SSC CGL Tier-I paper
SINCE is used only with perfect tenses, never with simple past
BETWEEN requires 'and' to connect two items (between A and B)
AT NIGHT is correct but IN THE MORNING/EVENING are also correct
