which are the documents we need to upload and is there a compulsion to upload original documents only for eg caste certificate?

Hello Gaurav, below is the list of all the requrired documents and yes it's neccassary to upload original docments.

• Scanned photograph and signature – CheckPhoto Size, Format and Other Details
• Valid Photo ID (Aadhaar Card/Passport/Driving License/PAN Card/Voter ID/College ID/Employee Identification Card/Notarized Affidavit with Photo, Signature, Date of Birth and Residential Address).
• For foreign students, Passport/ Govt. Issued ID/College ID/Employee ID will be the valid ID proofs.
• Degree Certificate/Provisional Certificate/Course Completion Certificate
• Copy of Mark Sheet of the 5th /6th /7th semester
• Final year students must submit Provisional Certificate Letter as per format issued by the Home of Institute/Dean/Registrar/Head of Dept.
• Candidates in the final year of AMIE have to submit their mark sheet for Section A of AMIE in case of professional equivalent qualifications.
• Caste Certificate (if applicable) as per given format
• Disability or PwD Certificate (if applicable)
• Candidates pursuing a higher degree or masters have to submit the qualifying degree certificate
