Personal suggestion: 1. Strengthen the training of basic mathematics ability, especially mental and oral calculation ability. I suggest you buy him a mental arithmetic and oral arithmetic for Grade Two, and finish one on time every day. After a while, you will be surprised.
2. Chinese knowledge depends on accumulation. I ask children below grade three to recite every text. In order to be able to dictate the new words in each lesson, you must supervise them every day.
Generally speaking, you should worry more. When the children get used to it, you will relax.
I wish your child good grades.
