If you write poorly, you will be deducted points, generally 2 to 3 points, if there is no topic, a quarter will be deducted, if it is irrelevant, only 1 will be given, if the sentence is unreasonable, 4 to 5 points will be deducted, and if it is less than 100, 0.5 points will be deducted (for example, if it is less than 1, 4 points will be deducted).

The above is my experience, I hope it will be useful to you.
