Yes, it will be acceptable. In GATE registration, the name should match your valid photo ID proof in terms of spelling, not the order. Many Indian IDs have surname written first, while the portal generates it as first–middle–last. Since all three parts of your name (Vikash, Rameshbhai, Bhagel) are correct, there won’t be any issue. Just ensure you upload the correct ID proof. During verification, they check spelling, photo, and signature, not the word order.
