JEE 2023 (Joint Entrance Examination)

The JEE (Joint Entrance Examination) serves as an entrance examination for securing admission into numerous engineering colleges nationwide. In the year 2023, the National Testing Agency (NTA) will oversee its administration, conducting the exam in four sessions. Recognized as one of the most arduous entrance exams in the country, JEE 2023 serves as a pathway to esteemed institutions such as the IITs, NITs, and Central Funded Technical Institutes (CFTIs). The JEE is divided into two parts, each with its own significance.


Admission criteria for institutes such as the Indian Institutes of Science Education and Research (IISERs), Rajiv Gandhi Institute of Petroleum Technology, and the Indian Institute of Science include the marks obtained in JEE Advanced as one of the determining factors. However, it’s important to note that these institutes are not included in the central IIT-JEE Advanced counseling process.


  • Eligibility for JEE (Main) 2023 includes individuals who cleared their Class XII exam or any equivalent qualifying examination in 2022 or 2023.
  • Candidates currently appearing for their Class XII exam or any equivalent qualifying examination in 2023 are also eligible for JEE (Main) 2023.
  • A maximum of two consecutive years is allowed for candidates to appear for JEE Advanced.
  • Individuals holding a Diploma are now eligible to apply for JEE, but specifically for admission to IITs.
  • Diploma holders applying for JEE must also appear for the JEE Advanced examination.


Depending on the location of the examination center, each paper in JEE Main and JEE Advanced can be attempted in English, Hindi, or other languages. It’s important to note that the patterns of the JEE Main and JEE Advanced papers also vary from each other.
