How do you reply to como el la clase in spanish???

Welcome to the forum, attention to detail is very important in learning a language.

In English, we use "an" not "a" in front of answer: I need an answer.

The question you ask is non-grammatical, potential answers could include things like:

¿Cómo?, ¿Mande?, or ¿Qué quieres decir?

For the question:

¿Cómo es la clase?

You would give a description of what the class is like, your choice of what to say would be partly driven by who is asking of course.
