Cambridge English * * * level 3, strictly speaking, there is natural English of Cambridge English, and each level has two volumes A and B * * * six volumes, and level 3 is the most difficult. If your English is good, I suggest you learn new concepts. Starting from the second volume, Cambridge and New Concept One are suitable for students from grade four to grade two. And if you read three or four volumes, it will be much more convenient to go abroad in the future, and it will be much easier to read IELTS!

I hope I can help you!
