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.

The term "upper class" typically does not require a hyphen when used as a noun or adjective in most contexts, such as "the upper class" or "upper class citizens." However, it can be hyphenated as "upper-class" when used as a compound adjective directly before a noun, for example, "upper-class families." Always consider the context to determine if hyphenation is necessary.
