First, this is an imperative sentence-- it gives a command. The subject of the sentence refers to the person or persons being told to perform the action-- "class" (in other words, the command is being given to the members of the class). The predicate means the verb-- the action word. So, what is the speaker (probably the teacher) asking the class to do? The action word here is "read." The class is being asked to "read" something, and that is the simple predicate.

Class is the simple subject. Did have is the simple predicate (verb).
The simple subject is the implicit pronoun "you", the natural subject of an imperative mood verb such as this sentence contains. "Class" is an appositive to the unstated "you" and should be followed by a comma, as is normal for an appositive that is the first word of a sentence.
Class is subject; begins is predicate
