Don't take part in extracurricular training courses, as long as you are serious and diligent. Go to a key high school as usual! !
Many students apply for training courses, but it's actually nothing ... The reasons are nothing more than these: First, their grades are poor, and then they study in training courses; Second, attend the training class and let someone supervise the study; Third, lay a solid foundation.
In fact, all this can be done at home by yourself. The key depends on your attitude towards learning! ! Attitude determines height, determines the height of your grades and determines the height of your life! !
In addition, if you don't know how to ask the teacher, become a frequent visitor to the teacher. Isn't that enough?
