Let's learn something now!
‘A piece of cake’– something is very easy.
CONQUER English school will make learning English a piece of cake.
‘Let the cat out of the bag’ – to accidentally reveal a secret.
I let the cat out of the bag about CONQUER English school to my friend and now her English speaking is excellent!
‘To cost an arm and a leg’– something is very expensive.
I am so excited because this English class at CONQUER English school doesn't cost an arm and a leg. I am going to start now!
