Use rounding to eliminate obviously wrong multiple-choice options when exact calculation takes too long. The "Three-Pass" Testing Strategy
This phase is where you transition from a math student to a TMSCA competitor.
| Concept | Formula / Description | | :--- | :--- | | Simple Interest | ( I = P r t ), or total ( A = P(1+rt) ) | | Triangular numbers | Sum of first n positive integers: ( \fracn(n+1)2 ) | | Mean (Average) | Sum of all terms / Number of terms | | Median | The middle value when numbers are arranged in order. | | Mode | The most frequently occurring value. | | Range | Largest value - Smallest value | | Least Common Multiple (LCM) | The smallest positive number that is a multiple of two or more numbers. | | Greatest Common Factor (GCF) | The largest positive integer that divides two or more numbers without a remainder. | General Math Tmsca Study Guide
Look at the multiple-choice options before solving. Sometimes, estimating or checking the units digit of the answer choices can eliminate three or four options without requiring you to do the full calculation.
The Texas Math and Science Coaches Association (TMSCA) General Mathematics contest is one of Texas's most demanding academic competitions. It challenges students from middle school through high school to solve a wide range of mathematical problems in a high-pressure, 40-minute environment. This study guide is designed to help you navigate the test's format, master its scoring system, and implement a strategy to achieve a top score. | | Mode | The most frequently occurring value
Pass 1: Scan the test from questions 1 to 50, answering only the absolute easiest questions that take under 20 seconds.
The contest consists of either 50 questions (middle school) or 60 questions (high school), and you have exactly 40 minutes to complete them. This means you have less than a minute per question, so speed and accuracy are critical. | Look at the multiple-choice options before solving
Fly through the test answering only the "gimme" questions—the ones you can solve in under 20 seconds.
