Can You Explain The Ending Of Core Connections Algebra: Second Edition, Version 5.0, Volume 1?

A month before the SATs, I, Jenny Reid, could see my score. Literally. It was just floating right above my head. But there was a catch. Every time I cracked open a prep book, my score would drop by ten points. But if I skipped a day of school? It jumped right back up by ten. So, I played the system. For a whole month, I barely lifted a finger. And on the day of the test, the number glowing over my head was a solid 1560. When the scores finally dropped online… I'd scored a 500. And the 1560? That was my little sister Patricia's score. My parents lost it. As punishment, they got me a grueling night-shift job at a local electronics factory. That first night, a bunch of guys I'd never seen before cornered me in the parking lot and beat me half to death. Fading in and out of consciousness, I heard my sister's voice right by my ear. "You just had to one-up me, didn't you? Thought you were so smart… but you never figured out I was the one controlling that number over your head." The truth hit me like a physical blow. The score had been her trick all along. I opened my eyes—and I was back. One month before the SATs. The number above my head read exactly 1300. "Hey," my sister said, all fake sweetness. "Want to study together tonight? We can go over the practice tests." I looked at the stack of papers in my own hands. Without a word, I pulled out my lighter and set them on fire right there in the driveway. "Exams are coming," I said, watching the flames. "I'm not studying." My score ticked up to 1310. My sister's face was this perfect mask of disappointment, but the second I turned away, I caught the sly smile she couldn't quite hide. She had no idea… the real performance, the one I'd been rehearsing just for her, was finally about to begin.

I have always had an almost pathological sense of paranoia. Ever since I was a child, I was convinced that the people around me were out to get me. Back in elementary school, when everyone was lining up for their student ID photos, I flatly refused to have mine taken. I insisted that the district office was going to use my picture for identity theft. The situation escalated so badly that the principal had to personally sit me down and spend half an hour trying to convince me otherwise. Then, there was the fingerprint registration system in middle school. The school required every student to submit their fingerprints to access the campus buildings. I was so terrified that someone would steal my biometric data that I literally rubbed the skin off all ten fingertips to make them unreadable. Even when my fingers were bleeding, I kept shouting that they were trying to steal my identity. I would rather climb over the school fence every day than cooperate. Every relative I had called me crazy. My parents were so fed up that they seriously considered having me admitted to a psychiatric hospital. I did not care. I guarded my privacy with obsessive determination, gritting my teeth and holding my ground all the way up to the eve of the final exams. Then came the day before the exam. That afternoon, our homeroom teacher, Tracy Collins, walked into the classroom carrying a metal lockbox. A warm, motherly smile spread across her face as she set it down on the desk. "Everyone," she said, "to make sure nobody forgets their documents tomorrow, I'd like you to hand over your IDs and exam admission slips for safekeeping tonight." She patted the lockbox reassuringly. "Tomorrow morning, I'll personally return them to each of you outside the testing center. This way, there's absolutely nothing that can go wrong." The class was deeply moved by her thoughtfulness. Some students even looked close to tears as they eagerly pulled out their documents and lined up to hand them over. Everyone except me. My hand clamped down over my pocket so tightly that my knuckles turned white. Cold sweat poured down my back. A sharp alarm bell was ringing in my head. Trying not to attract attention, I fished out a spare flip phone from my bag, ducked beneath my desk, and dialed emergency services. As soon as the call connected, I lowered my voice and spoke into the receiver. "Hello. I'd like to report a crime. My name is Charles. "I believe a teacher at St. Alden High is working with an identity-fraud ring and is planning a large-scale operation tonight involving examination fraud and identity theft."

The day before the SAT, the homecoming queen, Madison Freeman, lets out a shrill scream. "Everyone, you should skip out on the test! Luna AI is paying out five million dollars!" She pulls up the insurance agreement she has signed with Luna AI on her phone and shows it to everyone. As long as we miss the SAT, we will get five million dollars in compensation. "We're all Acorn League material. Skipping the SAT just means repeating senior year." "This is five million dollars we're talking about. We could work our butts off our whole lives and never earn that much." In my previous life, I had called 911 and spent forever explaining that Luna AI was just an AI and couldn't actually pay out. The cops literally dragged every single person into the exam hall. But because of it, Madison was ridiculed and cyberbullied so hard that she couldn't take it anymore and jumped off a building. The whole class then cornered me on the rooftop and poured acid all over me. "If it weren't for you, Madison would still be alive." They watched me thrash in agony and then kicked me off the edge. When I open my eyes again, I am right back at the moment Madison is hyping everyone up to blow off the SAT. I quietly watch every single one of them sign the agreement with Luna AI. I can't wait to see who they plan on collecting those five million dollars from.

On the day of the SATs, all the students in the exam hall were asleep. The teachers did not just let them be, but they also told everyone not to write any answers. For the past ten years, every valedictorian in the city had mysteriously died on the very day their scores were released. The police conducted thorough investigations but found that all of them had died by suicide. Students across the city were gripped by fear. Some transferred to other schools, others dropped out. Some even deliberately underperformed on the exam. They were all equally terrified of becoming the top scorer and valedictorian. I was the only one who did not care. I was already at the bottom of my class. I would barely even qualify for a community college, let alone the SATs, which I had left completely blank. But to my surprise, when the results came out, I turned out to be the top scorer!

The 100th time Dexter Carrington ditches me to help my best friend with her lab work, I write the final line in my diary and break up with him. Dexter is exasperated, to say the least. "I genuinely don't know how your amygdala is wired. Your emotions have completely bulldozed your rational thinking." My best friend, Brianna Holt, laughs. "That's cruel. You're insulting her intelligence in words she can't even understand." She's right. I don't understand. The two of them dominate the biology department rankings every year, taking first and second place, and are the kind of prodigies even their professors defer to. I'm just an ordinary student at the music school next door. When they talk about how cells have their own rhythms, the only thing I can think to ask is what time signature those rhythms are in. Dexter always hates that. "If you don't understand, don't chime in." So now I listen. I don't chime in anymore. Because the first page of this diary reads, "Today is my birthday, but Dexter chose to go over data with Brianna. "By the time this diary is full, I'm leaving him for good."

We had been together for seven years, yet my CEO boyfriend canceled our marriage registration 99 times. The first time, his newly hired assistant got locked in the office. He rushed back to deal with it, leaving me standing outside the County Clerk's Office until midnight. The fifth time, we were about to sign when he heard his assistant had been harassed by a client. He left me there and ran off to "rescue" her, while I was left behind, humiliated and laughed at by others. After that, no matter when we scheduled our registration, there was always some emergency with his assistant that needed him more. Eventually, I gave up completely and chose to leave. However, after I moved away from Twilight City, he spent the next five years desperately searching for me, like a man who had finally lost his mind.
