+
+## what happened
+
+submitted an unedited version of a final presentation video for calc. the wrong file. the one with mistakes still in it.
+
+## why it's a gotcha
+
+you have the right version and the wrong version on your computer. they have similar names. you're rushing. you grab the wrong one and hit submit. you don't realize until it's too late — or worse, until the grade comes back. this happens with code submissions, video projects, essays, applications, everything.
+
+## the fix
+
+always preview/watch/re-read the exact file you're submitting before you hit send. open it. watch the first 30 seconds. read the first paragraph. confirm it's the right version. name your files clearly — "calc_video_FINAL.mp4" vs "calc_video_draft2.mp4." the 60 seconds of checking saves you from a mistake you literally can't undo.
