JEE Main is India's most attempted engineering entrance exam with 12–14 lakh students per year — arguably the world's largest competitive exam by participation. The result is reported as a percentile score (not raw marks), normalized across multiple shifts and sessions. The best percentile from Session 1 or Session 2 is considered for the final merit list. Paper 1 is for B.Tech/B.E. admission; Paper 2A for B.Arch; Paper 2B for B.Planning.

💬 What Aspirants Say — Real Reviews
"People think numericals are safe because there's no negative marking — that's completely wrong for JEE Main. Both MCQ and numerical sections carry −1 for wrong attempts. I lost 8 marks guessing numericals in my first attempt. Learn from my mistake."
"The percentile system means you don't need to score 300. Getting 180–200 consistently is enough for a decent NIT. The key is being consistent and making fewer mistakes than your peers — not necessarily solving the hardest questions."
"NCERT Chemistry is literally the exam syllabus for Inorganic. I read every NCERT line, did past papers, and scored 90+ in chemistry consistently. Don't skip NCERT for any JEE coaching material shortcuts."
