Harry Potter X reader: Can't help who I am

Chapter 3

You woke up before everyone else in the dorms. You put on your robes and do your make up. You look over your schedule one more time before heading to the great Hall. You eat alone because nobody but the professors are up and about. You eat eggs toast and bacon. You finish it by gulping a big cup of orange juice and you head to your first class, potions! You get there before anybody else and you take a seat somewhere in the middle. You already were advanced in all your classes due to your homeschooling but you still had to do the first year classes even though you could easily make better potions then some of the professors. You sat in the room for about 20 minutes before Snape walked in and smiled at you and went to his podium  at the front of the room. "Ah Mrs. Y/l/N nice to see you are so excited to be in my class. You smile and say "it's my favorite of all the classes, of course I'm excited." " would you like do a potion before anybody else shows up?" He asks. HEL.... I mean I would love too!" You correct yourself just in time. He asks what level potions you can make and you say "I can make potions better than anyone in this school."  Snape raises his eyebrow "so you think."  You laugh. " oh I know!"  " then Mrs. Y/L/N I challenge you to a potion off!!" " Challenge accepted." You say with a grin. He tells you to get your caldron out and set up at one of the two tables in the front. You do so and he sets his up. By the time it's all ready about half the class are in their seats watching curiously. You look around and see Raven, Draco and Pansy. You smile at them. Then Snape told everyone to shut up. Once everyone was quite he told them that we were having a potion off. You heard several snickers and people say things like " who does she think she is." Or "she is so stupid." Those remarks right there set your mind to where you were going to show all these idiots what you could do. Snape told you that we are making the hardest potion ever created, liquid luck , fast version.  He said that you and him have the whole class period to finish it  starting now.  With a flick of your wand all the ingredients were on your table. So were Snape's. You've done this before so you knew what you were doing. You started putting things together and in 30 minutes you had the perfect gold glittery liquid luck. Record time. Snape was still going a stirring his. He was actually quite close behind. So once he finished his they had to test which one worked. Snape brought out two Fairies and poured his liquid luck on the fat one and your liquid luck on the tall one. The fat one started steaming and disintegrated.  The tall one turned into the prettiest Fairy ever. Snape turned to you with pride and confusion because you have beaten him. "Mrs. Y/l\N you have beaten me!! You will now be the second teacher in this clas if you want it. You looked at your class mates. Which there jaws were on the floor. You smiled and said "I would love too!!!!
