IOH Student Survey Filler

Install Chrome

Any recent Chrome build is fine. Nothing else to install — Go runtime, drivers, etc. are already baked into the exes.

Allow Mongo Atlas access from the machines you'll run on

Atlas → Security → Network Access → Add IP → Allow access from anywhere (0.0.0.0/0).

Seed MongoDB with the 5913 UG rows — do this once on one machine

Open PowerShell in the folder that has upload.exe + student_needed.csv + student_answer_pool.json and run:

.\upload.exe -type studentCopy

Expected output: inserted 5913 student docs inserted 6 answer-pool questions done

This drops and rebuilds the ioh.student collection, so only do it once.

Open the dashboard (one terminal)

.\monitor.exe -coll studentCopy

It auto-opens http://localhost:8080 — live counts, per-worker activity, retry buttons.

Smoke test — one row, visible browser, no actual submit

.\filler.exe -type student -count 1 -dryCopy

You'll see Chrome open, walk through the Zoho pages, and stop at the Submit button.

Submit one row for real

.\filler.exe -type student -count 1Copy

Takes ~60 seconds. The monitor will flip that row from in_progress to done.

Go wide — all remaining rows, 10 parallel Chromes, headless

.\filler.exe -type student -tabs 10 -headlessCopy

Run this on as many machines as you want. Each row is claimed atomically from Mongo, so no duplicates ever.

Human-paced (15–20 min per response — looks natural)

.\filler.exe -type student -tabs 5 -headless -pace-min 15m -pace-max 20mCopy

The 5-minute per-row cap auto-extends to pace-max + 5 min, so slow pacing won't cause timeouts.
