1. I didn't learn math well in primary school, and now it's exposed!

The child hasn't adapted yet.

……

The most important thing to sign up for a remedial class is to see if the child is willing or not, or if the teacher you are looking for is strict. If not, the child is particularly disgusted and there is no need to let him (her) go to the remedial class! As a person who has participated in many remedial classes, I have a deep understanding of this. If children really learn something in it, they are either willing to learn it themselves or the teacher manages it well!

I hope my answer is helpful to you!
