**A: I have an extra class in the morning, an extra class at noon, and an extra class in the evening; and I totally have 3 more classes.**

Can I rephrase Sentence A into Sentence B?

**B: I have an extra class in the morning, at noon and in the evening.**

Is there a word in English which emphasizes "an extra class" can associate with morning and noon and evening?

I feel I need something like "each" or "respectively", but how do I write it? like "**I have each extra class in the morning, noon and evening**"?
