# GATE 2020 Syllabus for Mechanical Engineering | All the information that you need

Indian Institute of Technology, Delhi is the conducting authority for **GATE 2020 exam** and the official notification along with GATE 2020 syllabus has been announced recently. GATE, which is an acronym for Graduate Aptitude Test in Engineering is basically an examination on the comprehensive understanding of the candidates in various undergraduate subjects in Engineering/Technology/ Architecture and post-graduate level subjects in Science.

GATE 2020 will be conducted for 25 subjects and it would be conducted on the following dates in the month of February 2020.

**1st February 2020****2nd February 2020****8th February 2020****9th February 2020**

GATE 2020 will be a purely **computer-based test (CBT). **It is **important **to note that GATE 2020 **score will be valid for THREE YEARS **from the date of announcement of results.

In addition to admission in Postgraduate Programs in central government supported institutes, sevel Public Sector Undertakings (PSUs) will also use GATE 2020 score to shortlist candidates for filling up Graduate Engineer Trainee (GET) or Management Trainee (MT) vacancies.

**It should also be noted that DIRECT RECRUITMENT to GROUP A level posts in Central government, like Senior Field Officer (Tele), Senior Research Officer (Crypto) and Senior Research Officer (S&T) in Cabinet Secretariat, Government of India, is now being carried out on the basis of GATE score. You can find the details of these posts in major National newspapers/Employment News.**

Some important points to note:

- All exams for 25 subjects in GATE 2020 will be CBT.
- A candidate can appear in
**only**one paper of his/her choice. - The entire application will be done
**online**on the GATE 2020 website. Click**here**to check it out. - A new paper called "
**Bio-medical engineering (BM)**" will be introduced in GATE 2020.
