Joint Entrance Examination (JEE) Advanced is considered to be one of the toughest exams in the world. Conducted by one of the seven Indian Institutes of Technology (IITs) every year, the exam aims to test the engineering and intellectual aptitude of candidates. Therefore, candidates who successfully clear this exam can indeed be called the “cream of Indian intellect”.
Looking at this paper, students often wonder where the questions come from. Answering this question is a YouTuber named Vinay Uppal, who gained significant popularity due to his “Untold Stories of JEE Advanced 2020” Physics debunking video.
During his IIT JEE video, Uppal stated four important sources from where the questions were asked. These are – 1. Research Papers, 2. Undergraduate Textbooks, 3. Topics in engineering and 4. Veritasium Videos. To justify his claim, Uppal mentioned multiple questions from last year’s paper and their corresponding sources.
According to Uppal, a question in JEE Advanced 2020 Paper 1 came from a research article published in the Proceedings of the National Academy of Sciences of the United States of America. Another question clubbing frictional force and distance came from a video uploaded by Veritasium on YouTube.
A question regarding kinetic frictional force was asked last year’s JEE Advanced examination. This same question was taken from the research paper titled “Moving fingers under a stick: a laboratory activity” published in 2011. Another possible source for the question can be a book called “Mechanics (Volume 1)” written by a legendary physicist named Arnold Sommerfeld. Candidates can refer to the chapter “Mechanics of System” to view the question.
A train-tunnel based question asked candidates to find force “N” has been taken from two research papers, according to Uppal. The first research paper is A Review of the Piston Effect in Subway Stations published in 2013 in the “Advances in Mechanical Engineering” journal. The second paper is Fluid Mechanics of Train-Tunnel Systems in Unsteady Motion published in 1971 in the journal named “AIAAJ”.
The IIT entrance exam paper also featured a question based on Stokes-Einstein’s Relation and Ficks’ Law of Diffusion. Both these concepts are being taught in the undergraduate course of Chemical Engineering. So clearly, IITs are looking at the undergraduate curriculum to test JEE Advanced aspirants.
A common concept taught in the mechanical engineering curriculum is the “Principle of Arago’s Disc”. A question based on this concept also made it to last year’s IIT entrance exam. This is another indication that authorities look at the undergraduate engineering syllabus to create the JEE advanced paper.
Uppal also stated that 3 questions from JEE Advanced 2020 were similar to those in the book called “Pathfinder for Olympiad and JEE Advanced Physics”. The book, created by Arvind Tiwari and Sachin Singh is relatively new in the market and a useful recommendation for JEE Advanced 2021 aspirants.
This YouTube video by Vinay Uppal garnered a considerable amount of attention and appreciation from aspirants. Many students even encouraged Uppal to continue making these debunking videos for future JEE Advanced exams as well.
The national-level entrance exam has a set syllabus but there are no limitations on the level of difficulty. Therefore, such debunking videos are incredibly useful in helping aspirants crack the JEE Advanced 2021 examination.
