Rest it is your journey, you have to put day & day out hard work. Don't put extra pressure on your parents + Don't appease your mind that CSE is only possible from DELHI or XYZ cities. Previous toppers need to speak clear & loud.

2. From traditional education system :need coaching/tution for every step.
3. From unethical advertisement : using previous years toppers pic to promote their institute.
