If you want to find a way to do math, you have to practice more questions (I practiced from 1 in those years until now, and only got 100).
I'm not sure about the admission score. I only know that the second volume of grade five accounts for 20%, the first volume of grade six accounts for 30%, and the second volume of grade six accounts for 50%. The admission score of previous graduates is 194. (You can get extra points for participating in the activities of the Education Bureau)
It is better to read no.1 middle school.
Finally, which school are you from?
