求翻译：Whether you are at an advanced level, have little or no knowledge of English, or are somewhere in between, you are placed in the class that is right for YOU. At each level, students work on listening, speaking, pronunciation, reading, writing and grammar. At the end of each semester, all students who regularly attend classes and successfully complete their assigned work receive an official certificate. Our teachers give personal attention to each student and evaluate individual progress throughout the semester. Classes are small, encouraging maximum participation. Students have access to various labs on campus for additional practice.是什么意思？
