I am 22 years old and I have recently started preparing for SSC CGL. My goal is to get selected within the next 3 years at any cost, and I want serious and practical guidance about how to achieve it. Please tell me how many hours I should study daily, what kind of routine and mindset I should follow, and what mistakes I must avoid during preparation. I also want advice on how to stay consistent for a long time, avoid distractions and procrastination, and improve my speed and accuracy in all subjects. Please guide me honestly like an experienced mentor instead of giving only motivational lines.
