🎯 Test prep
Practice in the exact format of each test: the SHSAT, TACHS and ISEE. No calculators, real timing.
ISEE Quantitative Reasoning
ISEE Mathematics Achievement
SSAT quantitative
only if a school asks for the SSAT📐 Formulas to know by heart
The SHSAT gives no formula sheet.
- Rectangle:
- area = l × w · perimeter = 2l + 2w
- Triangle:
- area = ½ × base × height · angles add to 180°
- Trapezoid:
- area = ½ × (b₁ + b₂) × h
- Circle:
- area = πr² · circumference = 2πr = πd
- Box (prism):
- volume = l × w × h · surface = 2(lw + lh + wh)
- Cylinder:
- volume = πr²h
- Right triangle:
- a² + b² = c²
- Polygon:
- interior angles add to (n − 2) × 180°
- Percent change:
- (new − old) ÷ old × 100
- Simple interest:
- I = P × r × t
- Distance:
- d = rate × time
- Slope:
- rise ÷ run = (y₂ − y₁) ÷ (x₂ − x₁)
