Take a look at the sentence again:
George would have __________ to class sooner, but a beautiful woman was
listening to him lie about his fat wallet and hot car, and he couldn't tear
himself away from the conversation.
The sentence requires the past participle of come, an irregular verb. Come is the past participle.
Verb | Simple Present | Simple Past | Past Participle |
come | come(s) | came | come |
Commed, the form you chose, is a spelling error. Before you continue, review the rules for irregular verbs.
