Hey Anup.

See any of the competitive exam doesn't see the condition from which u are coming. It only recognised the effort u have made to crack them. If u are from a middle class family then u only have to work hard to make ur family economically stable and balanced.

Clearing any of the competitive exam for btech career requires rigorous practice of the questions that are asked in the exam including the time management. U should be solving more and more unsolved papers to clarify ur weak points. U should be using short notes and formula book for any query.

Hope u got ur point. Feel free to ask.

Good luck
