Need Urgent Advice

I started my jee journey from the start of class 11, did everything consistently and never missed any lecture. Now barely 1 month is left for my jee mains and my marks in mock tests are fluctuating between 110-120. They are neither going up nor going down. I don’t know where i went wrong in the past 2 years but seeing the score, i don’t think that i will get into an NIT. So, anyone who has given jee or is giving jee with me, pls give me some advice so that i can boost up my score to 170-180…….
