💡 Expert Tip
Read the trade code table carefully before registering — a candidate can apply for only one trade or discipline across this entire notification, and applying to more than one will get all your applications summarily rejected. Also, since there's no written test here, your percentage of marks in the qualifying exam directly decides your merit rank, so make sure any CGPA or grade on your marksheet is converted to an equivalent percentage certificate from your university in advance, because this conversion is mandatory at document verification and missing it can cost you your seat. Codes 101-103, 108-111 need NAPS portal registration while codes 104-107 need NATS/BOAT registration — using the wrong portal for your trade code is a common rejection reason. Finally, don't skip Step II: submitting the Microsoft Form is compulsory even after applying on NAPS/NATS, and incomplete Step II means your application won't be considered at all.
