How do I actually book my dMAT test centre slot, and what should I have ready before I start?

You create an account on the official g.a.s.t. registration portal once registration opens, and enter your personal details exactly as they appear on your passport; mismatches here cause delays not just at the test centre but later in your APS process too.

The Booking Steps

Choose your preferred test-centre city from the list of available locations shown at that moment, since availability changes daily as other applicants register. Pay the exam fee during registration itself, confirm your slot, and save your login details, as your results and certificate will be downloaded later through this same account.

What to Have Ready Before You Start

Before you start, keep ready: your valid passport, proof of your undergraduate degree (provisional certificate or final marksheet showing your specialization clearly), your Class 10 and 12 marksheets (mainly for the wider APS file), an active email address, and an international payment method enabled for foreign-currency transactions.

My Advice

Gather every document on this checklist into one folder before you sit down to register, and have your payment method already confirmed with your bank. Registration typically takes under 15 minutes when everything is ready in advance, versus a stressful, interrupted process when you are hunting for documents mid-session.
