What happens if I select the wrong dMAT Subject Module during registration?

You correct your selection through the g.a.s.t. portal before your registration closes. There is currently no confirmed process to switch modules after the exam date itself, so the window to fix a mistake is limited.

Fixing It Before Registration Closes

As long as your registration window is still open, you can change your module choice in the g.a.s.t. portal. Once the exam date passes, there is no confirmed route to correct it, so treat the open window as your only reliable opportunity.

When You Are Unsure Which Module Applies

If you are unsure which module applies to you, particularly for borderline degrees like B.Sc. Statistics, integrated MBAs, or dual-major programs, get written confirmation from APS India or directly from your target program before registering rather than guessing based on subject name overlap.

My Advice

Double-check your module selection immediately after registering, not weeks later. If something looks wrong, fix it through the portal right away while your registration window is still open; waiting until closer to the exam date removes your ability to correct it at all.
