My Nightly Grind Turned Sis Into a Prodigy

I'm infamous for being the stupidest student in the entire school. Even though I've been doing additional revisions till late night every day, I keep getting the lowest rank consistently in exams. On the other hand, my younger sister, Mia Lawson, doesn't study at all. Yet, she always comes up as the top of her grade every time. Our parents soon call her as the Math Prodigy. Because of that, I'm forced to live in the attic, which leaks all the time during rainy days. My table lamp gets smashed into pieces as well since I shouldn't be wasting power if I can't cram any knowledge into my brain. My parents also force me to drop out of school and start working at a young age. They claim that losers should stick to their paths and do what they do best. But at the same time, they don't hesitate to drop a grand sum of money just to enroll Mia into a class based on the Arithmetiad. There's a time when I contract a high fever that makes me all woozy and my consciousness all blurry. Because of my illness, I randomly draw an incorrect construction line on a draft paper. The next day, the line actually appears on Mia's exam paper, pixel by pixel. That's when realization dawns on me immediately. Before the day the National Arithmetiad is set to be streamed live in front of the entire nation, I opt to not solve any difficult questions. Instead, I lock my room door and keep telling myself in front of the mirror that the greatest mathematical equation in this world is 1+1=3.
