IIT JEE: Your Guide to Preparation, Branches, and Exam Secrets

When you hear IIT JEE, India’s most competitive engineering entrance exam that opens doors to the Indian Institutes of Technology. Also known as Joint Entrance Examination, it’s not just a test—it’s a filter that decides who gets into the country’s top engineering schools. Every year, over 1.5 million students take JEE Main, but only about 20,000 clear JEE Advanced to even be eligible for an IIT seat. That’s less than 1.5% success rate. This isn’t luck. It’s strategy, stamina, and smart choices.

Behind every IIT JEE aspirant is a web of decisions: Which subject should you push harder? Is Physics Wallah enough, or do you need coaching? Should you chase the most famous branch or pick one that fits your strengths? And how much sleep can you really afford to lose? These aren’t just questions—they’re make-or-break factors. The JEE Mains, the first stage of the exam that qualifies you for JEE Advanced and admission to NITs, IIITs, and other engineering colleges tests speed and accuracy. The JEE Advanced, the harder, deeper exam that only the top JEE Mains scorers take to enter IITs rewards deep understanding. Then there’s the IIT branches, the specialized engineering fields like Computer Science, Mechanical, and Electrical that determine your career path and starting salary. Some pay more upfront. Others demand more sweat. And no one tells you which one is truly the hardest—until you’re stuck in the middle of it.

What you’ll find here isn’t generic advice. It’s real talk from students who cracked the exam, failed it, and tried again. We cover how much sleep actually helps your scores, which IIT branches pay the most, why some subjects matter more than others, and whether Physics Wallah can replace a coaching center. You’ll see the full list of 23 IITs in 2025, how JoSAA counselling works, and why choosing a branch isn’t just about prestige—it’s about what you can handle. This isn’t about memorizing formulas. It’s about building a plan that fits your life, your limits, and your goals.

Let’s cut through the noise. You don’t need another motivational quote. You need clear, practical answers. Below, you’ll find detailed guides that match exactly what you’re dealing with right now—whether you’re starting out or in your final push. No fluff. Just what works.
