How to Download GATE Score Card 2021?

GATE results are declared by the conducting authority before the release of scorecards. This is only to tell if a candidate has cleared the exam or not. However, the final GATE score card carrying the candidate's overall score and rank is released after five days of result declaration. Take a look at the below steps to check download GATE scorecard from GOAPS website:

• Visit the official website of GOAPS 
• Login using the registered credentials 
• Click open GATE 2021 scorecard link 
• Candidate's scorecard with the GATE rank and overall score will be displayed on the screen 
• Download and take a print out of the same for future reference 

Details Printed on GATE 2021 Score Card
A candidate's GATE score card comprises the following details: 

• Candidate's name, photograph, and signature 
• GATE registration number

What is GATE Normalisation? 
The GATE exam is held in both single and multi-session for a few papers. This is because such papers have a large number of aspirants. Due to this, the conducting body has to use the process of normalization to ensure unbiased results in multi-session GATE paper.
The process of normalization in GATE is based on the assumption that the ability of candidates is equally distributed across all sections in a multi-session exam. It is the responsibility of the exam conducting body (IIT Bombay for GATE 2021) to ensure that the number of candidates in each session is of the same magnitude. The process of normalizations will be different for single and multi-session exams. The raw marks of a single session will be used to compute a candidate's GATE score whereas, the marks in the multi-session exam will be normalized and then used to compute the final GATE score. 

GATE 2021 answer key along with the official question papers for all 25 papers will be released by IIT Bombay after the exam is concluded. The test takers can access the GATE answer key on the official website of GOAPS. To be able to check the same, candidates will have to log in on the official website using their registered credentials. According to the official website of GOAPS, the answer keys are finalized by the GATE committee. No emails and telephone calls will be entertained on this matter.

The exam conducting authority will release the provisional GATE 2021 answer key first along with the candidate's response sheet. Test takers can check and download their response sheet by entering enrollment ID/email address/registration ID and GOAPs password in the login window. The final answer keys for GATE are made available basis the objections received from candidates.

Steps to download the GATE answer key:
Step 1: Visit the official website
Step 2: Login using registered credentials
Step 3: Check and download the GATE answer key
Step 4: Also take a print out for future reference  

After the release of the provisional GATE answer keys and response sheet, candidates get the opportunity to raise objections if they are not satisfied with the released answer keys. The exam conducting body takes the objections into considerations and if the objections are found genuine then the official answer key will be revised. 

Candidates who wish to raise objections against the GATE answer key need to fill an online form. Follow the below steps to access the online form and raise objections:
