Idiom: To Burn the Midnight Oil
I’m going to really have to burn the midnight oil tonight if I want to pass my test tomorrow.
Marianne and I burned the midnight oil last night to finish the project on time, and then the boss didn’t even need it today!
If you’re burning the midnight oil before a test tomorrow, well, go to bed. In the last 24 hours before an exam, anything you learn will probably not make it into your long-term memory, so you won’t remember it for the test. Plus, you’ll be tired, which means a lower grade. So go to bed, and next time, don’t wait until the last minute!
