the combination of all the subject
First, find the subject of the sentence. In this case, the subject is "all," which is a plural subject. It refers to a group-- All boys; all girls; all Americans, etc. But I know what is confusing: "of the class." The short answer is, don't worry about it. Any time you see words like "of", "in", "to", "with," etc, these are all prepositions and this means there's a prepositional phrase coming. Examples: of the class, in the room, at the bus stop, with my friends...-- these are all prepositional phrases. The reason I am mentioning this is a prepositional phrase cannot be the subject of a sentence. For example: the color of his eyes is blue. (Eyes is not the subject. Color is the subject. As for "eyes," it is part of a prepositional phrase-- "of his eyes", and it cannot be the subject. If there were no prepositional phrase, you could say His eyes are blue.) So, just make the prepositional phrase vanish, and you have the subject all by itself. Thus, All (ignore "of the class") are good.
