I asked attendees at Mythmoot XII what their undergraduate degree is in. I got 41 responses, for a total of 53 majors. As you can see, we came from all over. I lumped all the engineers together1 and though they were all different kinds, together they made up a plurality of 5. Communications was next with 4. Then came English Lit and History with 3. Everyone else was all alone.
Update: Late returns are coming in, and I’ve combined the variants of English into one category. We’re up to 60 degrees now. English is now the top spot with a whole 10% of the sample. Engineering and Communications are #2 and #3, followed by Classics and Physics with three people each.
This post will be updated as new responses come in.

I could have added Classics and a History, and Lee could have added English

Latin here!

Does that count as Classics?
