PU refers to the language scores that need to be provided when applying for studying abroad. If the applicant's PU score is not enough, the school will generally provide corresponding help. For example, the school may provide language courses or take other language exams for applicants to help them improve their PU scores. In addition, some schools will provide scholarships or other financial assistance to help applicants complete their study abroad plans.

In addition to the help provided by the school, applicants can also improve their PU scores through their own efforts. For example, you can take language training classes, teach yourself or take other language exams to improve your language level.
