The beautiful Getty Center - and it’s always free!
Take the Metro Rapid from the stop at the corner of Bellagio and Sunset, and get off right at the entrance. There is free admission, but you have to pay $3 for the roundtrip bus fare.
Go Saturday night, they are open late! Go view many paintings, and some natural art as well: the sunset over LA is a breath-taking view.
Good luck on your midterms everybody!
