In case/if • We use in case when we do something in order to be ready for future situations/problems. • Compare: I’ll accept the job offer If it’s well paid. = I won’t accept the job offer if it’s not well paid. I’ll accept the job in case I don’t get any other offers. = I will accept anyway, because there might not be any other offers.

Second Conditional • Would/wouldn’t +VERB (without to) If + PAST SIMPLE Or If + PAST CONTINUOUS

Compare 1° and 2° Conditional • If I have time, I’ll help you. = a possible situation. I may have time. • If I had time, I’d help you. = an imaginary/hypothetical situation. I don’t/won’t have time. Remember here: I’d = I would

But if you did things would be different. • Eg: If you had studied more, you would have done better in your exams. = you didn’t study enough, so you failed.
