IIT Guwahati BS Admission 2026: Upload Class 12 Marksheet and IAT Score by July 3; Important Deadline for Applicants
Students seeking admission to the Bachelor of Science (BS) programme at IIT Guwahati for the 2026 academic session have received additional time to complete an important step in the admission process. The Indian Institute of Technology (IIT) Guwahati has extended the deadline for uploading the Class 12 marksheet, detailed Class 12 subject-wise marks, and IISER Aptitude Test (IAT) 2026 score. Eligible candidates can now submit these documents through the online admission portal until 12:00 PM on July 3, 2026.
The extension provides relief to students who were waiting for their IAT results or had not yet completed the document submission process. Candidates who fail to upload the required documents before the revised deadline may face difficulties in the admission process.
IIT Guwahati Extends Document Upload Deadline
IIT Guwahati is offering admissions to its 4-Year Bachelor of Science (BS) programme in Biomedical Science and Engineering through IAT 2026 scores. The institute has asked all candidates who have already submitted their application forms to log in to the admission portal and upload the necessary academic documents within the stipulated time.
The revised deadline is:
- Last date to upload documents: July 3, 2026
- Time: 12:00 PM (Noon)
Candidates should avoid waiting until the final hours, as heavy traffic on the portal could lead to technical issues.
Documents Required for Upload
Applicants are required to upload the following documents:
- Class 12 marksheet
- Subject-wise Class 12 marks
- IAT 2026 score
- Any other document specified by IIT Guwahati during the admission process
Students should ensure that all uploaded documents are clear, readable, and match the information provided during the application process. Incorrect or incomplete details may result in rejection of the application.
Why the Document Upload is Important
Uploading these documents is an essential part of the admission process. Although candidates may have completed the online application earlier, IIT Guwahati requires academic records and IAT scores to verify eligibility and prepare the admission list.
The institute will use these details to evaluate applicants according to its admission rules. Candidates who do not complete this step before the deadline may not be considered for admission.
Therefore, applicants should carefully verify every detail before final submission.
