Is it better to use Qidong Middle School as the math exercise book for grade three or to meet the class standard?
You can choose according to your own situation. Different counseling books have different emphases. If you need to improve, you should choose more difficult exercise books. If the foundation is not very good, you should choose an exercise book based on basic knowledge. If you have enough time, you can try it, so that you can sum up the key points of the topic yourself and study better.
