Indian Institute of Technology (IIT), Delhi has opened the facility for application form correction of GATE 2020 from October 15. Candidates can now make the changes related to their name, father's name, college name etc in the submitted application form by log in to their GOAPS account during the GATE application form correction period. Candidates will also be required to pay an additional fee to make corrections in the GATE 2020 application form. Registered candidates whose application has error should make sure that they make the necessary GATE 2020 application form correction within the specified time period. Later, the candidates will also be able to change details like exam city, Gender, Category, PwD Status, Dyslexia status, other similar learning disabilities etc. The candidates can also make changes in the marked defect(s) which includes Name, DOB, Details of Parents /Guardian, Correspondence address and Qualifying in application form form for exam of GATE

I hope this helps

Is their are any job vacancies in PSU sector for btech manufacturing engineering students .If their are any vacancies then in which branch code they should give GATE exam ???

Aman Raj Student Expert 16th Oct, 2019

Hello Sorabh

It is directly or indirectly related with ME. So

If you like thermal, apply for ME, If you don't like thermal apply for PI.

In other terms, if you like manufacturing and management - apply for PI.

You must know that seats for ME in IIT's are 900+ whereas for Manufacturing and production it is around 150+ only.


gate from correction last date please tell me

Papeya Dubey Student Expert 16th Oct, 2019

what is the last date for uploading the eligibility form ? actually i have the defect in eligibility college reopens at 21/10/2019.thanks in advance

Aditi Amrendra Student Expert 16th Oct, 2019

IIT Delhi has started GATE application correction window from October 15, 2019. Modifications in the basic submitted information can now be done by the candidates in online mode.Dont worry you will get time for correction because there is no last date provided for correction window but i would suggest you to get the correction done as soon as possible.

I hope this helps.
