So, how long have you studied? General training institutions rarely drop out of school in the middle of class.
If my major is really popular at present, and my brothers and sisters have a good job, I suggest that I choose my major and bite my teeth. If it is only difficult at present, it is recommended to apply for reconstruction with the school. If you are struggling from the beginning, it means that your foundation is not enough to support you to study this major. You can consider asking for a major change.
If none of the above is true, apply for a refund. It is not easy for training institutions to refund now, but it is still possible to cancel classes after patient consultation with each other.
If the other party refuses to refund, then consider reasonable rights protection.
