Prepare by section rather than treating Bain TestGorilla as one generic aptitude test.

The exact assessment can vary, so the invitation and instructions you receive should be your source of truth. Your preparation should match the skills and formats listed there rather than assuming every candidate gets the same mix.

If your assessment includes numerical, verbal, or critical-thinking components, practice those separately first so you can see which one is actually limiting your score under time pressure.

Review your invitation, list the sections it specifies, and run timed practice for each one. Track accuracy and time separately so you know where to focus. CaseBasix's Bain guide is here: Keep a short note of what improved and what still broke so the next practice session has a clear purpose.
