JEE (Joint Entrance Examination) Main is one of the most challenging and coveted entrance exams in India for engineering. Every year, the exam is conducted by NTA for candidates seeking admission to various undergraduate programs offered by the premier technical institutes of the country.

JEE Main consists of two papers named Paper 1 and Paper 2. Paper 1 is conducted for students seeking admission to Undergraduate Engineering Programs (B.E/B. Tech) at IIITs, NITs, other Centrally Funded Technical Institutions (CFTIs), and Institutions/Universities funded/ recognised by participating State Governments. Paper 2 is conducted for students seeking admission to B. Arch and B. Planning courses in the Country. JEE Main also serves as an eligibility test for JEE (Advanced), which is conducted for admission to IITs.

For the session 2023-24, JEE Main is conducted in two sessions. Session 1 was conducted in January 2023, and session 2 is scheduled for 06, 08, 10, 11, and 12 April 2023. The exam is conducted in 13 languages in computer-based test mode at designated exam centres in India and abroad. Since the competition is sky-high, it is imperative for students to prepare effectively, for which adequate knowledge of the syllabus and chapter-wise weightage is critical. Here we present the complete syllabus, chapter-wise weightage, important topics, previous years’ analysis and exam tips to help students ace their exams.

JEE Main 2023 Exam Tips:

As mentioned above, JEE Main is among the most challenging engineering exams. Therefore, rigorous preparation, revision, practice and effective exam strategy are critical for students to qualify. To help students, we present some tips and strategies to improve their exam performance and score.

  • Remember to sleep early the night before. Wake up early the following day, exercise mildly and eat a light breakfast or meal.
  • Reach the examination centre at least 15 minutes before the reporting time. Don’t forget to carry your admit card and ID proof with you.
  • Carefully read all the instructions provided in the admit card and question paper and listen to the additional instructions provided by the invigilators.
  • Start with the easier section/ questions first and leave the tougher ones for later on.
  • Read the entire question carefully before answering it.
  • Utilize the step-by-step approach for numerical questions. First, gather all the given data, identify the concept/ formula, and start solving the problem.
  • For conceptual questions, carefully read the entire question and all options before deciding on the correct answer.
  • Do not guess answers, as there will be negative markings that could actually reduce your score.
  • Keep an eye on the clock. Do not waste too much time on the initial questions.

JEE Main 2023 FAQs by NTA:

Since the JEE Main 2023 exam is just around the corner, candidates are advised to go through the provided chapter-wise weightageimportant topics and previous years’ analysis and prepare accordingly for the exam.
