Hi! This response might be late but thought to still share some insights.
My Kindergartener was also waitlisted #2 (tier 3) for NTA and Lenart. NTA offer came first which we declined and rejoined the waitlist for Lenart. Lenart offer eventually came through on the next offer day which was about 2 – 3 weeks ago. If your kiddo hasn’t received an offer yet, you might want to reach out to either school to see if there are any more spots available. Goodluck.
