I am a 3rd year undergraduate, many companies are coming for internship in my college but i am unable to clear coding round of a single company. I practiced for around 4-5 months on leetcode and did 330+ question on leetcode, but still. in coding round I perform poorly than my Batchmates and now I started feeling that I am very dumb and all my Archivement till now are fake and i dont know anything. what should I do now, how should I study
Please anyone guide me!!!!

Update -- Thanks everyone for motivating me!! It really means a lot to me, And i am very happy to tell that finally I got a intern in a very good company and through this I learned a lesson that hard work never gets wasted☺🙂
