How seriously do MBA students actually take pre-class prep/reading?

I’m curious about pre-class prep culture across MBA programs.

Given how central case studies are to the MBA model, I’ve been wondering how seriously pre-reads are actually taken.

Lately, I’ve noticed more students tend to skip full readings and rely on AI summaries instead.

What’s it like at your school?

• Do most people actually read the assigned cases/articles?
• If not, why- volume, density, time paucity?
• If they do read, what drives it- grades, cold-calling, or genuine interest?

Also, for schools using collaborative tools like Perusall, do they genuinely improve engagement?

Would love to hear your experiences.
