Eliot's Temporal Trouble

Eliot slumped onto his chair, the dreaded 'F' glaring back at him from his science exam. "This is a disaster!" he muttered. He had been studying for weeks, but the complex equations and theories just wouldn't stick. Then, his eyes fell on his half-finished time machine in the corner of his garage. A mischievous idea sparked in his mind.

With trembling hands, Eliot set the time coordinates to the day before the exam. The machine whirred and sputtered, then with a flash, Eliot found himself back in his younger self, Ethan's, room. "Ethan, listen carefully!" Eliot exclaimed. "On the science exam, the answer to question 3 is 'E=mc²,' and question 7 is 'Photosynthesis.'" Ethan stared at him, bewildered.

The next day, Eliot nervously awaited his exam results. When the teacher announced the scores, Eliot couldn't believe his ears. He had aced the test! A wave of relief washed over him, but it was quickly replaced by a nagging feeling of guilt. He knew he hadn't earned that grade fairly. Later that week, Doctor Aris approached him, his face grim.

"Eliot," Doctor Aris began, "we've detected temporal anomalies consistent with your time machine's activity. It appears you shared future knowledge with your past self." Eliot's heart sank. "Time travel is a delicate science, Eliot. Your actions have created a paradox, and more importantly, you cheated. As a result, you are hereby banned from all future time travel experiments." Eliot's dreams of scientific glory vanished in an instant. He learned a valuable lesson that day: some mistakes, even with time travel, can't be undone, and honesty is always the best policy.
