Whenever you need to study for an important test, google "site:edu [subject] exam". My econ teacher just taught me this trick. If you go to google and type in "site:edu production possibilities curve exam" for example, you get many different college exams featuring problems pertaining to that subject. And if you need to write a paper about something, just add filetype:pdf
