Relatively speaking, the red stripe score is more relaxed, but you can't go back on your word after signing the contract, while the white stripe requires a high score, but there is more room for choice.
The red stripe was signed before the entrance examination, which is a kind of independent enrollment agreement. If the child is good enough and signs a red stripe, as long as the score of the senior high school entrance examination reaches the distribution score of high school, it can be incorporated into the key classes of the school.
