Core Concept

Read this first — the foundation of the topic

→Core Concept

Tenses have three main times: Past, Present, and Future

→Each time has four forms

Simple, Continuous, Perfect, and Perfect Continuous. This gives us 12 total tenses

💡Key Rules

Simple tenses show basic actions. Continuous tenses show ongoing actions (use -ing). Perfect tenses show completed actions (use has/have/had + past participle). Perfect Continuous combines both (use has/have/had + been + -ing).

🔢

Formula Block

Memorise — at least one formula appears in every paper

Present Simple: Subject + V1 (s/es for he/she/it)

Present Continuous: Subject + is/am/are + V1+ing

Present Perfect: Subject + has/have + V3

Past Simple: Subject + V2

Past Continuous: Subject + was/were + V1+ing

Past Perfect: Subject + had + V3

Future Simple: Subject + will/shall + V1

Future Continuous: Subject + will be + V1+ing

Future Perfect: Subject + will have + V3

Exam Patterns

What examiners ask — read before attempting PYQs

⚡Shortcut 1 - Time Signal Words

1

Identify time signal = 'since' indicates duration from past to present

2

Since + point of time = Present Perfect

3

Subject 'She' + has + V3 Answer: has been working (Present Perfect Continuous for ongoing action) Worked Example 2: Q: By the time you arrive, I _____ (finish) my homework.

1

'By the time' indicates completion before future point

2

Future Perfect needed

3

Subject 'I' + will have + V3 Answer: will have finished Shortcut 2 - Third Person Singular Rule: For he/she/it in Present Simple, add 's' or 'es' to verb. Words ending in s, sh, ch, x, z, o take 'es'. This is heavily tested in error spotting

⚡Shortcut 3 - Perfect Tense Helper Formula

Present Perfect = has/have + V3 (past to present connection) Past Perfect = had + V3 (past before past) Future Perfect = will have + V3 (completion before future point) Common Mistake #1 - The Biggest Trap: Students confuse Present Perfect with Past Simple

💡Remember

Use Present Perfect when past action connects to present (I have lived here for 5 years). Use Past Simple for completed past actions with specific time (I lived there in 2015). SSC exploits this confusion in 60% of tense questions. Another major error is using wrong helping verbs. Students write 'I am do' instead of 'I do' or 'She have gone' instead of 'She has gone'.

Always check subject-verb agreement carefully.

🔑 Key Points

12 total tenses: 3 times × 4 forms each (Simple, Continuous, Perfect, Perfect Continuous)
Since/For = Perfect tenses, Yesterday/Ago = Past Simple, Now = Present Continuous
He/She/It takes 's/es' in Present Simple (goes, watches, fixes)
Present Perfect = has/have + V3, Past Perfect = had + V3, Future Perfect = will have + V3
Continuous tenses always use 'be' verb + V1+ing (am/is/are/was/were/will be)
By the time/Before = Perfect tenses needed
Past Simple needs specific time, Present Perfect shows past-present connection
Error spotting: Check subject-verb agreement and time expressions
Never mix helping verbs: Don't write 'I am do' or 'She have gone'
Time signals determine tense: Always look for keywords like already, just, yet, still
