Thank you in advance.

Are these multiple choice options you've been given?

I would say "could he have". Yet, in the first place, I would be more inclined to say "I don't suppose he did well on the exam" if I wanted to say "did he". Likewise, "He almost failed to pass the exam" doesn't sound natural to me. I would say: "No, he almost failed it."

The whole sentence is a little awkward, but I agree with the above. Could he have and No.

If the verb is did do well --then use did he?

If it is could have done well --then use could he have?

I don't agree with the use of "could he have", it sounds awkward.

[...] he could have done well on the exam last week, could he have?
And if it is right, it sounds like the wrong question to me.

I would just use "could he" and "yes".

So I go with the latter, could/yes.
