The admission to the 23 IITs in India is on the basis of a Joint Entrance Exam called JEE ADVANCED which was formerly called as IIT-JEE from 1961 to 2012. The exam was rechristened as JEE ADVANCE or JEE ADVANCED from 2013 onwards. From 1961 to 2005, the exam was Subjective in nature but due to the RTI Act and its repercussions, the IITs made the exam into a machine-gradable Objective exam from 2006 onwards. From 2018 onwards, the JEE ADVANCED exam has become ONLINE too.
The JEE ADVANCED exam comprises of 5-6 different question patterns and changes every year. It is kept as a surprise and is not declared before the exam and hence the student needs to be trained for various different patterns. The JEE ADVANCED exam is thus a multi-pattern exam and its syllabus is same as that of the JEE MAINS syllabus from 2023 onwards. However, the difficulty level of the questions and the exam pattern is significantly more challenging than the JEE MAINS. So, a higher degree of problems solving ability and Test strategy is necessary to crack the JEE ADVANCED as compared to JEE MAINS. It is needless to mention that the JEE ADVANCED is the toughest Entrance exam in the world since 1961.
Based on past few years statistics, a score of 17.5 to 20% marks in JEE ADVANCED typically fetches an All India Rank (AIR) under 35000 in the Common Merit List (CML). However, this may vary as per the difficulty level of the JEE ADVANCED paper. A score of 70% marks and above usually fetches an under 1000 AIR.
The JEE ADVANCED exam format has 2 papers of 3 hours each in PCM in a single day typically from 9 am to 12 noon and again from 230 pm to 530 pm. The total number of marks in JEE ADVANCED varies between 360 marks and 420 marks.
