🔥 Exam Tip & The Advanced Conditional Cheat Sheet:
- Type 0 (Universal Truth): If + Simple Present → Simple Present.
Example: If you heat ice, it melts.- Type 1 (Probable Condition): If + Simple Present (V1) → will/can/may/shall + V1.
Example: If you study hard, you will pass.- Type 2 (Improbable/Imaginary): If + Simple Past (V2) → would/could/might + V1.
Example: If I had money, I would buy a car. (Note: Always use 'were' for 'be' verbs - If I were a bird...)- Type 3 (Unfulfilled/Impossible): If + Past Perfect (had + V3) → would/could/might + have + V3.
Example: If he had run fast, he would have caught the bus.- The Inversion Trick (Removing 'If'): TN Board loves this! You can remove 'If' by inverting the subject and the auxiliary verb.
👉 If I had known... → Had I known...
👉 If I were a king... → Were I a king...
👉 If you should need help... → Should you need help...- Unless = If + Not: "Unless you run, you will miss the bus" = "If you do not run, you will miss the bus."
