New Delhi: The submission process of the GATE application form 2020 has already been ended on October 5, 2019. In addition to the existing 24 papers, the authorities have added a new supplement to GATE 2020 in the form of biomedical engineering. Therefore, the syllabus for all 25 courses is available on the official website including the newly added paper of Biomedical Engineering. 

The GATE 2020 syllabus will help candidates understand important topics. Those who are interested to prepare for the national level entrance exam can use the GATE 2020 syllabus. The syllabus provided for GATE 2020 will make convenient for the student to plan and structure their study pattern.

GATE will be held in February next year by the Indian Institute of Science (IISc), Bangalore and seven Indian Institutes of Technology (Mumbai, Delhi, Guwahati, Kanpur, Harragpur, Madras and Ruki ).
