YouTube Shorts 149–154 (Study Skills) — download the .mp4 files

Right-click each link and choose "Save link as..." (or "Download linked file") to save a real .mp4 — do NOT grab from a file viewer, which saves .mhtml and YouTube rejects. This batch is the study-skills series in the new short format: every video runs 20–25 seconds with a natural loop (the final line connects back to the opening). Each link also has its upload metadata (title / description / tags) as a separate .md file — grab that too for the YouTube upload form.
