Does PLAY WITH GRAPHS Teach Problem-Solving Effectively?

To prevent me from being jealous of my stepmother's son, my dad implemented a "family point system". Washing dishes earned 1 point, and getting a perfect score on a test earned 10 points. Accumulating 1000 points meant you could make a wish come true. When my stepbrother broke a vase, Dad said it was a sign of good luck and awarded him 50 points. When I insisted on going to school with a fever, Dad said I was trying to garner sympathy and deducted 100 points. I scrambled to scrape together every point I could, all for that exorbitant Math Olympiad registration form. On the day I finally accumulated enough points, my stepbrother cried and said he wanted a pair of limited-edition sneakers. Dad immediately emptied my points. "We're family. Your points are your brother's points too." I looked at the torn-up application form and jumped from the 18th-floor balcony.

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.

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!"

Guess The Genre Book 2! There's a hidden motive behind the invitation of the game. The ten people who got dragged to the island will be "sent" to different dimensions to save worlds. Yenn, Byul, Jiwoon and the rest are first sent to an 'Easy mode' Arc a.k.a. a low level world as a tutorial for them. As they picked up talents and even abilities, all ten separate and was sent to different worlds by pair. Byul and Stanley got paired up and chose the Apocalyptic worlds. Both of them started to fight different kind of monsters, zombies, plants and etc. While they gone through thick and thin, both of them naturally got feelings of attachment towards the other. However, the attachment Stanley felt for him was something deeper than he imagined.

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.

My younger sister, Joey Crawford, and I have taken the exam 20 times in a row. Yet, our answer sheet shows the exact same answers every time. No matter how fast I complete the exam, Joey is able to turn in her paper one second before me. My homeroom teacher, Mr. Harris, has spoken with me three times regarding this matter. At the same time, I receive my first warning for cheating on the exams. Whenever my classmates see me, they say to me, "Hey, cheater! You got busted this time, huh?" The thing is, I've never even touched Joey's paper. How can our answers be exactly the same? During the college entrance exam, I suddenly awaken to the ability to see the live comments dangling in midair. "The female lead is the chosen one! It must feel amazing to have awakened the mind-reading ability and all!" "She relies on reading the side character's mind just to obtain all the answers. So what if the side character excels in her studies? Her role is to become the female lead's stepping stone to success!" It turns out that Joey has been stealing my answers by reading my mind this whole time. As I flip the exam papers over, I start singing the alphabet song mentally. "A-B-C-D-E-F-G…"
