Yes, in this case "seventh-grade class" should have a hyphen to show that the words "seventh" and "grade" are functioning as a single adjective modifying the noun "class."
No hyphen is needed for world class. World is just an adjective that describes class much like (for example) upper class, which also does not need a hyphen.
No
As with many compound terms, it depends on the usage and placement. In general, if the words are used as a modifier directly preceding the modified word, the hyphen is required. Otherwise the hyphen is not used. Examples: * "We use only first-class ingredients." * "Your presentation was first class." Style manuals such as Words into Type and Chicago Book of Stylehave chapters detailing hyphen usage, and they're excellent references for any writer or student.

Mama covers the books with brown paper so they look new and hands them out to her seventh grade class.
They shouldn't. They should all be required to take English class so that they can tell the difference between "there" and "their".
Elle est en classe septième.

The number 60 is written as sixty. Any number between 61 to 69, you add a hyphen after sixty then the word for the number.The class has sixty students.The new girl made sixty-one pupils in the class.
