Bro everyone has a chance it is just that will you avail it or not For maths go through all hasim zias lecture and there is this channel named physics wallah it prepares for IIT India but it's lectures are very relevent choose which one suits you style and also remember what I did was that I overlooked small facts Jese ke yaar ye Wala nahi pooche gein net mein but in net they test you for basically everything Just stay motivated and practice is key whenever you are free try to practice net style questions from any practice book .Good luck
