Mental Math and Estimation Final Checklist
Final checklist for mental math and Fermi estimation prep, covering arithmetic, statistics, market-making math, Fermi prompts, mocks, and review.
Candidates finishing mental math and estimation prep.
Arithmetic readiness
Fractions, percentages, multiplication, division, weighted averages, EV arithmetic, and units should be accurate before final mocks.
Statistics and market math
Review z-scores, variance, standard deviation, correlation, midpoint, spread, probability price, inventory, and simple PnL arithmetic.
Fermi readiness
For estimates, define target units, decompose drivers, use ranges, check scale, and identify the dominant assumption before presenting the final number.
Mock readiness
Run at least one mixed mock where arithmetic, estimation, and explanation happen together. Review the error categories immediately.
Common mistakes
Candidates often treat checklists as passive review. Use each unchecked item to assign a live drill before moving on to another topic.
Practice the pattern
Use the LeetQuidity curriculum and calibration to turn this topic into a focused practice plan.
