Aside from the MD, I guess it would depend on how you rate smart. Thor knows a lot of stuff about mythology, legend and other worlds and dimensions maybe even Dr Strange, let alone Iron Man or Reed would ever know.
Could he repair your DVD player? Maybe not, but then could Newton or Einstein?
Comic book intelligence is usually rated against technological and scientific know how the so called 8 smartest men thing is definitely all about this. But would you want Reed or Doom to take your appendix out (Doom would do it whether you wanted him to or not probably).
I'd say Thor knows a lot of stuff most people don't for sure, but by comics standard he's not even in the top fifty
