Algebra Gatekeepers: Schools deny advanced math to the highest-scoring students (educationprogress.org)

Over the past few months, I’ve been building 4KFilmDb, the first (and independent) 4K movie database to track and compare streaming quality (HDR, bitrates, Atmos audio) across platforms (Netflix, Prime Video, Disney+, etc).

Key features: • HDR & Atmos analyzers • Smart filters (Presets) with built-in options to suggest 4K titles or ready-made lists • Fake HDR titles tracker (spot poor HDR grades easily)

Currently in beta, so feedback is very welcome.
