Excel in or Excel at?

[Hunnybunny]

I was training some new teachers today and they posed this question:

Is it right to say "excel at"?

My first thought was to say "excel in". And then I realized that I do hear the former phrase too.

Are both of them right?
what's the correct answer to this:

"Chris excels in/at sports."

Now I'm confused.

Both 'excel at' and excel in' are (correctly) used.

If I understand the question correctly, you're asking whether it should be, "Chris excels in sports," or, "Chris excels at sports."

The answer is yes. It should be, "Chris excels in sports," or, "Chris excels at sports."
