The night before the college entrance exam results were released, I redeemed my Peking University ad

On the eve of the release of the college entrance examination scores, Ji Bai came across a post:
If I gave you ten dollars, how would you spend it?
1. Go back to ten years ago (6 yuan)
2. A house in Beijing (2 yuan)
3. Model figure (1 yuan)
4. Being with someone you like (5 yuan)
5. Peking University admission notice (8 yuan)
Ji Bai had seen too many of these wishful thinking posts, so he casually commented, "I choose 5+2, that's exactly ten yuan."
[Ding! System binding complete! Purchase successful!]
Ji Bai was stunned!
No, system, are you serious?
If we let a mediocre student like him get into Peking University, wouldn't his flaws be exposed in no time?
Until he saw the multiple-choice questions for the next day:
If I gave you ten dollars, how would you spend it?
1. Photographic memory (5 yuan)
2. Advanced Mathematics Proficiency (3 yuan)
3. Mastery of big things (3 yuan)
……
Ji Bai was relieved; it turned out the system offered a 10-yuan option every day!
Day 3:
1. During military training, the school beauty will bring you water (5 yuan).
2. The prettiest girl in your class will wipe your sweat during military training (3 yuan)
3. Nan Niang's roommate will wash your socks (1 yuan).
……
Day N:
1. Prove Goldbach's Conjecture (2 dollars)
2. Nobel Prize (5 yuan)
3. US President (8 yuan)
