Most realistic prep packages for BCG Casey, BCG CCA and Bain TestGorilla?

Hi everyone,

I would appreciate recommendations on which prep packages most closely resemble the actual assessments in question style, difficulty, timing and interface.

My shortlists are:

• BCG Casey: PSG Secrets, Prepmatter, MConsultingPrep.
• BCG Consulting Career Assessment (CCA): Prepmatter, CaseBasix, and SHL’s free practice tests for general familiarisation.
• Bain TestGorilla: Prepmatter, CaseBasix.

If you’ve recently taken these assessments or coached candidates who have, which resource would you recommend for each?

I’m also open to recommendations beyond the platforms listed. Please mention any affiliation with a recommended provider.

Thanks!
