She finished with twenty minutes to spare. She didn’t check her answers. She just sat there, feeling a strange, quiet peace.

The screen didn’t show a program. It showed a mirror. Not her reflection, exactly, but a slightly older version of her—maybe eighteen, with sharper cheekbones and tired eyes. The girl in the mirror was wearing a lab coat.

Results day. Aisha sat on her bed, Newton the hamster running on his wheel. She logged into the Cambridge portal. Her hands didn’t shake.

She had won. Not because she had cheated the future, but because she had understood the past. The ghost wasn't a miracle. The ghost was just a reminder: the science never really changed. It was always there—in the ocean, in the seed, in the circuit—waiting for someone to truly see it.

“Got it,” Aisha said, her hand trembling over her notebook. “Thank you. For everything.”

“Question seven, 2066,” Future-Aisha would say. “A seed germinates in a dark cupboard. After ten days, it’s pale and has long, thin leaves. Explain.”

It was brutal. But it worked. Aisha learned not just the what , but the why behind the mark scheme. She learned that a question about a simple pendulum could secretly be about energy transfer and precision. She learned that a diagram of a flower wasn't just about labeling the stigma and anther, but about the logic of pollination strategies.

Aisha’s heart stopped. “You… you have the answers?”

“I’m you,” the girl said. “Aisha Banerjee, valedictorian, Cambridge, Class of 2072. Well, I was. Now I’m a digital ghost, thanks to a quantum entanglement experiment gone wrong. But that’s not important. What’s important is that I’ve seen the 2066 Checkpoint paper.”

“Finally,” the girl said. “You’re late. I’ve been waiting since Tuesday.”

“If I have to calculate one more mechanical advantage,” she muttered to her pet hamster, Newton, who was busy stuffing his cheeks with a sunflower seed, “I will spontaneously combust.”

Seven marks. Just like the ghost had said.

She wrote. She drew diagrams of calcium carbonate shells sinking to the abyss. She detailed the equation for carbon dioxide dissolving in seawater. She didn’t forget the ocean.

The screen went black. The folder vanished. The laptop returned to being a useless grey brick.
