Anonymous......She didn't turn (at)(int0) the right street. It was the street after that she needed to turn (at)(into).

She didn't come at the right time. I have my mid terms and can't spend time with her.

I see no problem with the mixing of tenses in this example.
"Having my mid terms" can span a long period of time. It sounds natural to me.
At the time I write this, I'm still having my mid terms. I'm describing an incident which happened a day or two ago

To me, it's not an issue of mixing tenses. The sentence seems to be talking about the present. 'I have my exams and can't help her. I don't see it as past or conditional.

I see your point.
Learners frequently post examples which obviously have a context we're not privy to. It's a constant problem.
(Well, in this particular case we do have some context: There are two sentences, and the first one is simple past.)

AvangiThere are two sentences, and the first one is simple past.)

Yes, I meant that the second sentence isn't referring to the past and isn't conditional. So I chose "can't".
