Answer:
Using the correct punctuation marks, here’s the corrected version: I went over to Archie’s after dinner that day with Kevin. We weren’t in the official class, but we were welcome any time. He said, “My school is everywhere and always open.”
Step-by-step explanation:
In the first sentence, I added a comma after “day.”
In the second sentence, I capitalized the “T” to start a new sentence;
In the third sentence, I changed “were” to “we”;
In the last sentence, I added a comma after “he said.”
