I just finished my second year of high school in Beijing and want to go to Hebei for my third year of high school. Is this helpful for my college entrance examination?

It's up to you to help the Lord. If you are a person who can't discipline yourself, then I recommend you to go to Hebei. If you can arrange your own time and know what you should do, it is unnecessary.

Going abroad to study in senior three is nothing more than staying away from the noise and temptation. In this way, trying to find those closed schools, although it is very hard (the tactics of engaging in the sea in other places are very powerful, far from being comparable to those in Beijing), as long as you maintain a good attitude, there is still no big problem. It should be noted that people in a foreign land should not offend others. Whether you are a stranger or not, it is very important to improve the relationship between classmates and teachers, otherwise it will affect your study life.
