GATE Chemistry Syllabus 2023 PDF: Important Topics, Subject-wise Topics

By Abhinav Gupta|Updated : October 12th, 2022

GATE Chemistry Syllabus 2023 is divided into General Aptitude (GA) and topics from Chemistry (CY). The paper will be divided between GA and CY at 5% and 85%, ration respectively. Knowing the syllabus is the primary step to preparing for the GATE Chemistry exam. Thus, below we have simplified the GATE Chemistry syllabus and other important points that you must know.

It is unlikely that the administering committee would update the GATE Chemistry syllabus 2023, and it is likely to remain the same as in the previous exam. Candidates are advised to check the GATE syllabus for Chemistry (CY) before appearing for the upcoming examination.
