In which area did Peter Parker major in at university?
Did he ever show any computer hacking skills or other computer-related interests (computer science)?
The Marvel Universe Wiki reads:
Peter Parker graduated high school and earned a science scholarship to Empire State University (ESU) for achieving the highest scholastic average in Midtown High's history.
So while it doesn't say what the major was, it would have had to at least be science based.
ADDON: At some point (in Amazing Spider-Man) adult Peter Parker decides to leave the Bugle and teach high school science. There's a strong hint there.
According to the Game Spider-man. Shattered Dimension. He finished BS Physics. In the amazing universe though. Earth 616.
There is at least some very strong indirect evidence. To make his web shooters he needs some deep knowledge of chemistry. Additionally, I think at the earliest in The Amazing Spider-Man 6 his teacher Curt Connors is introduced. And it is stated clearly that he is a Professor of biochemistry. Another piece of indirect evidence that Peter Parker's major is chemistry or biochemistry. Later versions of the character differ from this. But the Peter Parker of the original (Lee / Ditko) run studied chemistry.
From everywhere I've seen, It doesn't mention what his major is. I would assume it was photo journalism based on his career with the Bugle, but he also showed an aptitude for biomechanics, engineering and biology. He might have double majored.
According to the Official Handbook of the Marvel Universe (Vol. 1 #10) Peter's major in college was Biophysics.
Latterly, the Official Handbook of the Marvel Universe (Vol. 4 #2) indicates that his Doctoral studies are in Biochemistry
Seriously, though, depending on which iteration of Spidey you pick, I would think something like mechanical engineering or (later) biochemistry.
I think his major was science because in the amazing Spider-Man, Peter Parker was the 2nd in class in Science, the 1st one was Gwen Stacy. And when he came to oscorp, dr curt Connors was delighted by his science knowledge. But creating the web shooters has something with engineering
Based off of all these, I'm just gonna assume that Peter studied as a Physics major, with a minor in Biochemistry (which tracks, given that that was Sue Storm's doctorate, and Peter was a longtime ally/fanboy of the F4). Also- even though Otto Octavius was controlling him so he didn't technically earn it- Peter has a Doctorate in Robotic Engineering.
