Application Cycle/ FAFSA

Hi! I am a current applicant hoping (&praying) to marticulate Fall 2026. I have finished up all my secondaries but I haven't heard anything back yet. I have 3 questions, please feel free to only answer a part anything is helpful & I thank u all in advance:

1. I haven't heard back from many DOs i applied to, not even a confirmation email since I submitted, do they have a different timeline than MDs?

2. I am determined and almost sure I will be starting in Fall 2026, should I submit my 2026-2027 FAFSA right now even though idk where I will be? I know it's the sooner the better and it just opened, has anyone experienced this situation?

3. Finally, I haven't heard back about interview invites, should I be worried?
