"There is a test tomorrow. I am nervous."

Translation: 明天有考试，我很紧张。

[Elmurza0110]

明天我有考试， 很紧张

[looli23]

Very weird structure, separating 很紧张 without a subject by a comma is just weird.

[Celticfiddleguy]

In English yes, but in Chinese that structure is very common - the subject (我) is obvious.

[ElizabethA286580]

I believe 明天考试, 我很紧张。should also be accepted. Since 明天有考试 is a very awkward way of expressing this.

[LeiFeiRalf]

Why do you feel it's awkward? It feels like most logical way of saying it to me.

[KX3.]

Same here, in fact the opposite is true.
