Build your practice
Your Bain invitation determines your actual assessment. These are CaseStar practice configurations—not a guaranteed Bain section list.
The 12-question sample stays free. Full runs use existing simulator access; coached interviews have separate access. Repeated runs may revisit question families with different values.
Eligible accounts can use one free full attempt across supported CaseStar simulators, not one per provider. Sign in and confirm availability before starting. The attempt is reserved when you start; you can resume that same run. Further full runs require appropriate simulator access. Free samples, lessons and their worked solutions remain available without buying.
The default CaseStar run has 48 questions: 12 each in numerical reasoning, critical thinking, working with data and problem solving. Each section has an unscored example and its own countdown; the review explains every answer. You can select fewer sections. These are practice choices, not a guaranteed Bain configuration.
Start with four numerical, four critical-thinking and four working-with-data questions, without signing up. Unscored examples and worked solutions are included. You can try fresh free sets; full practice uses separate simulator access.
No. This is independent practice using original questions. Bain assigns Sova or TestGorilla by invitation, and the exact sections vary. We reproduce documented provider mechanics where supported and label our own practice choices.
Each practice section has a hard deadline. Selected answers count only after submission. You cannot go back. Refreshing does not reset the clock. Bain asks candidates to complete TestGorilla in one sitting.
CaseStar does not request a camera, microphone or recordings for this practice. Bain allows pen, paper and a calculator for its digital assessment, but not a calculator in later interviews. Follow the instructions in your invitation.
No. Your results describe this practice set. They are not Bain scores, employer percentiles or a pass prediction. Behavioural familiarisation has no right answers or ideal-personality score.
