Cheat Sheet
- Modular Arithmetic and Remainders -
Understanding modular arithmetic is key for quickly finding remainders in a quantitative aptitude quiz. For example, knowing that 17 mod 5 equals 2 helps you solve cyclical patterns in seconds by "subtracting until in the house." Many university courses (e.g., MIT OpenCourseWare) use this foundational concept in number theory for efficient problem solving.
- Factorials, Permutations, and Combinations -
Revisit factorials to nail permutation and combination questions - recall that n! = n × (n−1) × … × 1, so 5! = 120. Use P(n,r) = n!/(n−r)! for ordered arrangements and C(n,r) = n!/(r!(n−r)!) for selections without order. Khan Academy's combinatorics modules offer clear visuals to cement these essential formulas.
- Divisibility Rules Simplified -
Memorize simple divisibility rules to spot factors without a calculator - any number ending in 0 or 5 is divisible by 5, and the sum-of-digits test checks for 3 or 9. For 7 or 11, use the alternating sum trick (subtract and add digits) to speed through math aptitude test questions with ease.
- Number Series and Pattern Recognition -
Training on arithmetic, geometric, and special series (like Fibonacci) sharpens your quantitative reasoning skills and pattern-spotting agility. For instance, given 2, 4, 8, 16, … you instantly recognize a common ratio of 2 - vital for many aptitude test questions.
- Approximation and Estimation Techniques -
Master estimation tools like rounding, fractional approximations, and Fermi estimates to tackle complex calculations under time pressure. A quick trick is approximating √50 as √49≈7 then adjusting by Δ/2√a, giving about 7.07 for rapid results. Official GMAT and GRE guides emphasize these strategies to boost speed and accuracy in quantitative skills assessment.
