The AIEEE was introduced in 2002, since the newly established NITs, IIITs and GFTIs wanted an entrance examination paper of a higher standard than the Common Engineering Test (CET), which was formerly used for admission to all non-IIT engineering colleges and some state government colleges also in few states, including even RECs and IIITs, owing mostly to the rising competition and the goal of ...
There were three questions comprising a total of 11 marks that were unclear. JEE(Advanced) has also been criticised for its notoriously tough, unpredictable paper pattern, for a high school student, the questions asked go way beyond the scope of conventional teaching in schools, this forces the students to opt for coaching classes.
JEE-Main, unlike JEE-Advanced, has a fixed exam structure and is not subject to change every year. Up until 2018, the JEE-Main Paper-I was three hours long and consisted of thirty questions in each of the three subjects (physics, chemistry and maths). 4 marks are awarded for correct answers and 1 mark is deducted for incorrect answers.
A total of 67 students achieved a perfect score, a significantly higher number than in previous examinations, which raised controversy. The National Testing Agency (NTA), the examination organizer, clarified that the higher number of top scorers was due to 44 of the 67 students answering a physics question incorrectly but still being awarded ...
From 2012, the old pattern was Phased out and the WBJEE would consist of only MCQ questions which differs from the previous years by the fact that 2 Marks Short answers type questions are replaced by MCQ with the same weightage of marks. In 2016 there will be a different type of pattern in Biology question paper. Category-I consists of (Q.1 to ...
A nuclear isomer is a metastable state of an atomic nucleus, in which one or more nucleons (protons or neutrons) occupy excited state levels (higher energy levels). ). "Metastable" describes nuclei whose excited states have half-lives 100 to 1000 times longer than the half-lives of the excited nuclear states that decay with a "prompt" half life (ordinarily on the order of 10
The three long-lived nuclides are uranium-238 (half-life 4.5 billion years), uranium-235 (half-life 700 million years) and thorium-232 (half-life 14 billion years). The fourth chain has no such long-lasting bottleneck nuclide near the top, so almost all of the nuclides in that chain have long since decayed down to just before the end: bismuth-209.
In combinatorics, the twelvefold way is a systematic classification of 12 related enumerative problems concerning two finite sets, which include the classical problems of counting permutations, combinations, multisets, and partitions either of a set or of a number.
