While calculating my chances, I realized that almost all my activities are tier 2 ones, with a few tier 3. I think I strongly need a tier 1 activity but don't know how to get there. And yes, I'm running out of time :/
I highly doubt you can have Tier 1 ECs in a few months. Besides, most AOs can identify intentional resume padding. If there are any math Olympiads, you can try that. Otherwise, just focus on other parts of your application.
