History of JEE (Main+Advance) Intermediate Course Isolation of Metals

The Joint Entrance Examination (JEE) is an engineering entrance exam conducted in India for admission into various undergraduate engineering programs. The JEE has evolved over the years and undergone several changes.

Initially, the JEE was conducted in two stages – JEE Main and JEE Advanced. JEE Main was conducted by the Central Board of Secondary Education (CBSE) and served as a screening test for JEE Advanced. JEE Advanced was conducted by one of the IITs and served as the gateway to admission into the prestigious Indian Institutes of Technology (IITs).

The syllabus for JEE Main and JEE Advanced included topics from Physics, Chemistry, and Mathematics. One of the topics in the Chemistry section was “Isolation of Metals”. This topic covered the methods used to extract metals from their ores and included topics such as roasting, calcination, smelting, electrolysis, and refining.

Over the years, the JEE has undergone several changes. In 2019, the National Testing Agency (NTA) took over the responsibility of conducting the JEE from the CBSE. The JEE Main exam was conducted twice a year, in January and April. The JEE Advanced exam continued to be conducted by one of the IITs.

In 2020, due to the COVID-19 pandemic, the JEE Main exam was conducted only once, in September. The syllabus for the JEE Main and JEE Advanced exams was also revised, with certain topics being added and some topics being removed. However, the topic of “Isolation of Metals” continued to be a part of the Chemistry syllabus.

In 2021, the JEE Main exam was conducted four times, in February, March, April, and May. The JEE Advanced exam was conducted in October. The syllabus for the JEE Main and JEE Advanced exams remained the same as in 2020, with the topic of “Isolation of Metals” continuing to be a part of the Chemistry syllabus.

Overall, the JEE has evolved over the years, but the topic of “Isolation of Metals” has remained an important part of the Chemistry syllabus. The JEE continues to be one of the most competitive engineering entrance exams in India, with lakhs of students appearing for it every year.
