Mental Math and Estimation Last Week Review
Mental math and estimation last-week review for quant interviews, focusing on error logs, light drills, mocks, and no-new-tricks discipline.
Candidates in final-week review mode.
Avoid new tricks
The final week is for reliability, not collecting new shortcuts. Use methods you can execute under pressure and explain clearly.
Review the error log
Choose the two recurring arithmetic or estimation misses that still matter. Assign one light repair drill to each and retest the next day.
Concrete final week
Do short arithmetic warmups, one Fermi prompt every other day, one mixed mock, and brief review after each session focused on repeat errors.
Keep practice light enough
Tired arithmetic can train bad habits. Stop drills when error rate rises and switch to review rather than forcing more volume.
Common mistakes
Candidates often cram volume in the last week. The better goal is fewer repeat errors and cleaner recovery in realistic mixed prompts.
Practice the pattern
