# IIT GATE 2020: introduction of a new document for biomedical engineering, see the program in detail

Consult the GATE 2020 program

GATE 2020: A new article on biomedical engineering introduced in the Graduate Aptitude Test in Engineering (GATE) from the year 2020. This should unify the undergraduate program in biomedical engineering of several universities and help to stimulate the growth of research and of product development in India, said a statement from IIT Madras who led GATE last year.

This year, Indian Institute of Technology (IIT), Delhi will proceed to the exam on February 1, 2, 8 and 9, 2020. Applications for it will start from September 3 on the official website, gate.iitd.ac.in. The online application process will close on September 24, 2019.
