I'm good senior high school, and I am in preparation for university selection test q is done in my country, and I've noticed that in practice math tests, my score has gone down by more than study (usually happened to me with the trials of other subjects even the college selection), although it is one of the best in the mathematics among my classmates and I do not know what to do, I have tried various methods study and none has served me and I do not know if those methods are what are not totally deficient or if I'm the problem. Q This is a fact that worries me because I really want to get a good score at the end of the year and to enter the race to study q desire (and also because math is one of the few things for which I'm really good). any suggestions are welcome. Thanks.
