班级的英语该怎么说

"Class" is the most common term used to refer to a group of students who are studying together in a school or educational institution. It is typically used in the context of a specific subject or course, such as "I'm in the math class," or "I have a science class next period."
In some cases, the term "grade" may also be used to refer to a group of students who are at the same level of education, such as "I'm in the third grade." This term is more commonly used in the United States, but may also be used in other English-speaking countries.
So, to answer your question, you could say "I'm in my English class" to refer to a group of students who are studying English together.
