GATE Syllabus 2020 for Chemical Engineering- Candidates who are appearing in GATE Chemical Engineering paper should be aware of each and every sections and topics that will be considered to prepare the question paper. Candidates should know GATE exam pattern and syllabus as they both are the base of preparation and candidate who know when to prepare and what to prepare is the one who win the race. So, grab all details from paper pattern to the important topics before starting the preparation.  

GATE 2020 is scheduled to be held on February 03, 04, 10 & 11, 2020 to provide admissions into M.Tech./Ph.D. programmes in IITs , IISc, IISERs and other reputed institutions. The Graduate Aptitude Test for Engineering (GATE) is a computer-based test with an allotted time of three hours. It consists of a total of 65 questions summing up to a total of 100 marks. As per the GATE syllabus, all the 23 papers have a section for General Aptitude questions, which will constitute 15% of the total marks. It will consist of two sections, Verbal Ability and Numerical Ability. The syllabus of GATE Chemical 2020 will give an overview of topics of all the sections of the examination. The engineering aspirants can plan their preparation as per the GATE syllabus for Chemical 2020
