Your sentences are mostly clear, but there are a couple of minor punctuation adjustments that can improve the overall flow. Here’s a revised version:
"I wake up at 7:00 AM, and I wash my face and brush my teeth. I attend my classes or study my lessons. I have lunch at 1:00 PM. After that, I study again. Then, I have dinner at 7:00 PM. I go to bed at 11:00 PM."
▎Changes Made:
1. Comma Addition: Added a comma after "7:00 AM" to connect the two independent clauses.
2. Comma Addition: Added a comma after "Then" in the last sentence for better flow.
3. Time Format Consistency: Added ":00" to "11 PM" for consistency with other times.
