Quoted as the “ controversial JEE question”, in this year’s JEE exam, there was a difference of opinion concerning the answer for the cylindrical furnace problem in the JEE Advanced 2023 Physics-Paper 2.
Conversely, The question arises, why are the answers from various coaching giants not aligned with the IIT solution key? Why was there a difference in opinion?

The fact that several prominent coaching institutes gave incorrect answers to this specific question raises significant concerns for students. It is apparent that these institutes, despite their assertions, lack the essential competence to adequately prepare students for this esteemed entrance examination, placing their prospects at risk. While these top institutes fail in identifying this gap, we’re proud to acknowledge the solution provided by Neelmani sir the Director of ISAC (Partnered with iScholar) Kota, a testament to his expertise, upholding iScholar’s vision of delivering quality education and personalized guidance to all our students.
Although the question was an extract of the MIT snippet, following the same concept, the solutions provided by various institutes were deemed not even close to the exact solution provided in the answer key.
Nonetheless, it is advised for future JEE aspirants and parents to run down the capabilities of the educators at any institution in the education system, before the admission process, to mitigate the possible off-road of the academic journey spawned by the institutes making unrealistic declarations.
