Most self-organized PMP study groups collapse by week 3. Not because people lack discipline — because the group has no structure that creates consequences for falling behind.

Here's the pattern I've seen building cohort-based certification programs:

The failure mode

A study group starts with 10-15 motivated people. By week 2, attendance drops. By week 3, the group chat goes quiet. Nobody officially quits — they just stop showing up. Six months later, half the group still hasn't scheduled their exam.

Why it happens

1. No diagnostic baseline. Everyone starts on the same material regardless of what they actually need to study, so half the group is bored and half is drowning.

2. No weekly deliverable. "Watch these videos" isn't a deliverable. There's no way to tell who's on track until the exam date arrives and someone isn't ready.

3. No social accountability loop. Study groups rely on willpower. Cohorts rely on visible weekly milestones (practice exam scores, live session attendance) that make falling behind obvious to the group, not just the individual.

What actually fixes it

• Start every student with a diagnostic exam in week 1 — it tells you exactly which of the 3 PMP domains (People, Process, Business Environment) they need to prioritize.

• Give every week one concrete deliverable — a timed practice exam block, not passive video watching.

• Build in two mock exams (mid-point and week 7) under real timed conditions — confidence, not just knowledge, is what fails people on exam day.

If you're running or thinking about running a PMP study group, the structural fix is almost always the same: less content, more checkpoints. Happy to answer questions on cohort structure in the comments.
