Idiom for IELTS

Rule of thumb

This is a rule that is not meant to be strictly accurate or reliable in every case.

As a rule of thumb, I go out every Saturday night. I didn’t go out last Saturday night and I can’t go out next Saturday night.

Remember that you won’t do yourself any favours if you simply throw these idioms into conversation during your IELTS interview. You must practice using them appropriately before the exam.
