Need Guidance regarding deferral process

Hi everyone,
Originally registered for CFA L1 this August but my Quants+CI+Ethics remain

So i am planning to defer to Nov attempt.

Kindly guide me seniors what is the process actually like and
More importantly will I get slots for November attempt? I am too anxious that are there slots available for deferred students?

I really appreciate your time and efforts to help a brother out 🫂❤️
