Lessons
- ~4 min→The PEMDAS RuleMaster the universal rule for evaluating any arithmetic expression. One mistake here kills 3-5 points on every GAT-E test.
- ~5 min→Fractions & DecimalsAdd, compare, and simplify fractions, and convert fluently between fractions and decimals — the backbone of half the quantitative section.
- ~5 min→PercentagesPercent of a number, percent change, and reverse-percent problems — one of the most frequently tested ideas on the GAT-E.
- ~5 min→Integers & Signed NumbersThe sign rules for adding, subtracting, and multiplying positives and negatives — a quiet source of avoidable errors.
- ~5 min→Factors, Multiples & PrimesPrime factorization and the GCF/LCM toolkit that powers fraction, ratio, and number-property questions.
- ~5 min→Squares, Roots & Scientific NotationRecognize perfect squares and cubes, simplify square roots, and read scientific notation at a glance.
- ~4 min→Estimation & RoundingRound to convenient numbers to eliminate wrong answers fast — a core no-calculator skill.
- ~5 min→Arithmetic Word ProblemsTranslate everyday English into arithmetic and choose the right operation with confidence.
- ~4 min→Absolute Value & the Number LineRead absolute value as distance from zero, and use it to handle "either sign" situations.
- ~5 min→Profit, Loss & Simple InterestCompute profit/loss percentages on cost price and simple interest with one clean formula each.
- ~5 min→Even, Odd & Consecutive IntegersUse parity rules and the algebra of consecutive integers to solve number-property puzzles fast.
- ~5 min→Remainders & Divisibility PatternsWork with remainders directly and use cyclic patterns to answer "what is left over" questions.
