Catching up on The Tower and need help

So I realized how far behind I am on The Tower challenges so I’m trying to slowly catch up and I’m doing Floor 40’s right now which is where you trail by 21+ with 4 minutes to go. How in the world is this doable now? I get it was probably doable back in the easy onside kick days but now I need at least 3-4 possessions in a couple minutes and this seems impossible. Anyone done these recently?
