The test was a piece of cake.
It was super easy.
We had to go inside, it was raining cats and dogs.
It was raining really hard.
She has butterflies in her stomach.
She's nervous
The student is busy as a bee
working really hard
He has his head in the clouds
He's not paying attention
He's really on the ball!
He's focused
She hit the nail on the head!
She did it perfectly! (She nailed it!)
I know the test is hard. Hang in there!
Keep going! You can do it!
Break a leg!
Good luck
Stop pulling my leg!
Stop joking with me.
