One-Week Mental Math Study Plan
A focused one-week mental math study plan for quant interviews, covering baseline checks, daily drills, EV, probability, mocks, and review.
Candidates with one week to improve arithmetic reliability.
Day one baseline
Start with a short diagnostic across fractions, percentages, multiplication, division, probability ratios, and EV arithmetic. Record error categories.
Daily drill shape
Use ten to fifteen minutes of mechanics, then one context prompt. Short reviewed sets beat long unreviewed sessions because misses become visible.
Concrete week
Spend two days on fractions and percentages, two on probability and EV, one on market-making math, one on a mixed mock, and one on final repair.
Keep the error log small
Each day should identify one repeated miss and one repair drill. A one-week plan cannot fix everything at once, so prioritize repeat errors.
Common mistakes
Candidates often cram new shortcuts in the final week. Reliability matters more than novelty when time is short and interviews are near.
Practice the pattern
Use the LeetQuidity curriculum and calibration to turn this topic into a focused practice plan.
