About JEE
The IIT JEE exam is one of the most prestigious exams for aspirants who want to pursue a career in the field of engineering. It is also one of the most difficult entrance exams to crack in India. The exam is mainly divided into two phases: JEE Main and JEE Advanced. NTA (National Testing Agency) is the exam authority for JEE Main. The exam will be held only two times in 2023. The first phase of JEE Main is expected to be conducted in the month of April, and the next session will be in the month of May. There are two shifts for the exam, including three papers – Paper I and Paper II A and Paper II B. The mode of exam is online, except for the drawing test, which is offline (penpaperbased) mode.
Students who clear JEE Main with a good score are eligible to get admission to various engineering institutes, like NITs, IIITs, and CFTIs situated all over the country. Furthermore, candidates who qualify for JEE Main with a high score and are in the top 2,50,000 will be eligible to appear for JEE Advanced 2023. The candidates who get a high score in JEE Advanced can get admission into one of the 23 IITs for various engineering courses.
