I only have one and a half days to review. Can you finish the knowledge of the third to sixth grades of mathematics in Guangzhou primary school?

Just look at the flowers.

Will the effect be bad?

It won't work very well. Relax.

Do you want to learn some olympiad?

It's best to learn some Olympic mathematics, but if you are afraid that the time is too short and you don't understand enough, you should do a few less questions.

Or do you want to make up for the past few days?

There is no time.
