I am going to explain to you what you need to do to be ready for a test.
When you do a test you need to be happy and you need to behave before you get to school. Being happy is nice and kind is going to help you get past the test.
Eat a healthy breakfast, for example here are some things you can eat for breakfast. Cereal and toast. everyday eating breakfast will make you have a good day and make you think.
Getting through the test will make you think because you ate breakfast. If you don't eat food that is junk food you will not be clever and smart.
So thats what you should do to prepare for a test.
