course.mit.edu

I'm Feeling Lucky sends you to the saved link, if there is one. If no one has saved a link, it will offer to run a Course Search for you.

If the saved link is not the main website for this term's class, try doing a Course Search and saving a different website.

If the correct website cannot be found in a Course Search, click here to add a new link using MIT Certificates.

course.mit.edu/6.001 will send you straight to the 6.001 page (I'm Feeling Lucky).
course.mit.edu/a/6.001 will send you to the search page for 6.001 (Course Search).
co.mit.edu works too. (for those who prefer a shorter URL).
If you prefer to use your browser's search bar, click on the search bar's drop-down search engine selector to add the "course.mit.edu" provider. The search bar will do an I'm Feeling Lucky search.
