What Are Common Mistakes To Avoid On The Linear Algebra Exam?

Mom is very biased. Every night, she will pour me a glass of milk before bedtime, simply because my grades are the best. My twin sister, Melody York, and my younger brother, Jason York, have never received this treatment before. On the night before my college entrance exam, Mom brings me a glass of milk before my bedtime as usual. But the next day, I end up collapsing in the exam venue even though I've always been healthy. Because of that, I miss out on the college entrance exam, causing me to fail. Meanwhile, Melody, whose grades have always been terrible, miraculously gets into an outstanding university. Mom consoles me, telling me that it's fine to just repeat the senior year. Every night, she prepares the same glass of milk for me as usual. Before the second college entrance exam, my cousin, Annie Wood, is staying over at my place temporarily. She wants to have a taste of my nighttime milk, only to get berated by Mom for being shameless. But halfway through the exam, I suffer from an intense stomachache all of a sudden. After that, I get sent to the hospital for emergency treatment. That year, I end up failing the exam again. But Annie, who comes from a vocational high school, gets into a pretty good university thanks to her scores. The entire family is elated, to say the least. But the fact that I have to repeat my senior year for the third time makes me the butt of everyone's jokes. I don't understand why all sorts of health problems will plague my body when it's time for my college entrance exam. When I'm taking the exam for the third time, I tell myself that this is my final chance, so I mustn't slack off no matter what. Three days before the exam, the only food I've ingested is the food offered by the school's cafeteria, just in case I run into more health problems on the day of the exam. But on the night before the exam, Mom brings me yet another glass of milk before bedtime.

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."

After I secured early admission to one of the country's most prestigious universities, my old high school invited me back to sit for the State Scholars Exam and compete for the top statewide score. But just ten minutes into the math paper, the proctor out of nowhere accused me of cheating. "Everyone else starts with the multiple-choice section. You went straight for the proofs. Were you planning to copy someone else's answers later?" Before I could explain a single word, he dragged me into the boys' restroom. Not only was I humiliated and forced to strip, I also had to let him inspect me over and over again to confirm that I had no cheating devices on my body. After I returned to the exam room, I decided it was better not to cause more trouble, so I started from the multiple-choice section like everyone else. But less than five minutes after I sat down, he yanked me up again. "This is even more fake. You didn't even take time to read or think through the questions before writing down the options. If that isn't cheating, what is?" "I suspect you knew the answers in advance. I'm reporting this to the exam board right now and having your exam qualification revoked!"

Flynn Watson, the actual heir of the Watson family, reported me for cheating during the exams. As I stared at both copies of the test papers with perfect grades and the same answers, I found it difficult to explain what happened. Everyone took Flynn's side. Because of that, I was painted as a cheater, which resulted in my exile from the Watson family. The Watsons went as far as to get me blacklisted from all industries just so they could appease Flynn. I ended up on the streets as a homeless person, where I got tormented incessantly. In a daze, I got hit by a car. I still failed to understand why my test papers would show the same answers as Flynn's even when I was on death's door. When I open my eyes again, I've gotten reborn on the day of the exams. This time, I choose to not write anything on the exam papers at all. I'd like to see just how I can be branded as a cheater now that I'm not given any marks at all.

The SAT was finally over, and our class gathered for a celebratory dinner when our homeroom teacher, Mr. Daniel Sanford, received an unexpected phone call. After hanging up, his expression turned grave. "A student in our class submitted blank answer sheets for every single subject." The room erupted in speculation as everyone tried to figure out who it could be. Then, to everyone's shock, the class president, Jayla West, approached me with tears in her eyes, apologizing over and over. She explained that one of the pencils she'd purchased for the class had been defective. Three hours after use, every mark it made would disappear—and by sheer bad luck, that pencil had ended up in my hands. In other words, I was the student who'd supposedly turned in a blank exam. Before I could say a word, my childhood friend and the school's top student, Samuel Ashley, stepped protectively in front of Jayla. "Ellie, Jayla didn't do it on purpose. It was an honest mistake. You're smart enough that even if you have to take the exam again, you'll still get into college. Stop blaming her." As I stared at the unquestioning way he defended another girl, a pang of sadness and bitterness shot through me. What Samuel had forgotten was that just before the exam began, we had swapped pencils.
