Understand how to calculate percentages of numbers and solve problems involving percentage increases and decreases. Word problems often mix all three of these concepts. So, you'll need to know how to interpret and solve these types of problems. Pay close attention to word problems that involve money, discounts, or taxes, as these are common on the ACT.
  • Ratios and Proportions: Setting up and solving proportions to find unknown values is an essential skill. These often show up in word problems dealing with rates, mixtures, and scaling. Ratios and proportions are extremely important in everyday life. Learn how to set up proportions and solve for unknown variables. Practice problems that involve finding unit rates, scaling recipes, or determining the concentration of mixtures. Practice is the key here. The more you do, the better you get.
  • Basic Algebra: Solving linear equations, simplifying algebraic expressions, and understanding inequalities. This involves simplifying expressions, solving for variables, and working with inequalities. You'll work with variables, exponents, and basic algebraic equations. Remember the order of operations (PEMDAS/BODMAS) to solve the equations. This is where things start getting a little more complex, but don't worry. Practice solving for variables in equations, simplifying expressions, and solving inequalities. This will boost your score.
  • Exponents and Radicals: Understanding the rules of exponents and simplifying radicals is essential. Practice simplifying expressions with exponents and radicals. Learn to add, subtract, multiply, and divide radicals. Familiarize yourself with perfect squares and cubes. Pay attention to problems involving square roots and cube roots.
  • Basic Geometry: Calculating the area and perimeter of basic shapes, such as triangles, squares, and circles. This also includes understanding angles and basic geometric concepts.

Strategies to Ace the ACT Math G01 Section

Alright, so you know the topics, but how do you actually ace the G01 section? It's not just about knowing the formulas; it’s about knowing how to apply them efficiently and accurately. Here are some strategies that will boost your performance and confidence on test day, guys.

Time Management is Your Best Friend

Time is of the essence! With a limited amount of time per question, effective time management is critical. First, be aware of how much time you have to spend on each question. Start by quickly scanning the entire section to get a sense of the difficulty level and the number of questions. Do the easier questions first. Don't waste too much time on a single problem. If you get stuck, move on and come back to it later if you have time. Keep an eye on the clock and try to allocate about a minute per question. Practice pacing yourself during your practice sessions. Take timed practice tests to simulate the test environment. This will help you get used to the time constraints and find your optimal pacing strategy. Regularly check how much time you have left during the test to avoid running out of time. With practice, you'll become more efficient in solving problems under pressure. Remember, it's about being efficient, not just right.

Practice Makes Perfect

I can't stress this enough! The more you practice, the more comfortable and confident you'll become. Solve a variety of problems covering all the topics in G01. Use practice tests and official ACT materials to familiarize yourself with the format and types of questions. Focus on identifying your weak areas and practice those concepts more. Consistent practice builds familiarity and improves your ability to recognize patterns and efficiently solve problems. Regularly review and understand your mistakes. Doing lots of practice questions will help you remember the concepts and the formulas you need to use, so you can do them on the spot.

Master the Basics

Sounds obvious, but it's crucial! Ensure a solid grasp of fundamental concepts. Double-check your calculations, especially with arithmetic operations. Mistakes in these areas can throw off your entire problem. Many problems are built upon these basic skills. If you do not have a strong foundation in these areas, you may struggle with even the most straightforward questions. Pay special attention to fractions, decimals, and percentages, as these often appear in a variety of problem types. Practice working with exponents and radicals, and make sure you know the order of operations (PEMDAS/BODMAS). This is very important. Always start with the fundamentals and build from there. When you have a solid grasp of the basics, more advanced concepts will be much easier to understand.

Know Your Formulas and Theorems

Memorize essential formulas and theorems related to geometry, algebra, and arithmetic. Have these at your fingertips for quick reference. Make flashcards or create a formula sheet. This will make it easier to solve problems quickly. You will need to know formulas for area, perimeter, volume, and other geometric calculations. Knowing the formulas will save you time and enable you to solve the problems more efficiently. Practice applying the formulas in different contexts. This familiarity will allow you to quickly apply formulas when needed, saving valuable time. Review them regularly and make sure you know how to use them.

Use the Process of Elimination

When you're stuck, use the process of elimination to narrow down your choices. Eliminate answer choices that are clearly incorrect to increase your chances of getting the correct answer. This strategy is especially helpful when you're unsure how to solve a problem. Even if you can't find the exact answer, you can often eliminate choices that don't make sense or are clearly wrong. This can improve your chances of guessing correctly. This can be especially useful if you are running out of time. Always make a guess if you have eliminated some choices, even if you are unsure of the correct answer.

Understand the Vocabulary

Become familiar with mathematical terms and vocabulary used in G01. Understand the definitions of key terms. Knowing the definitions of mathematical terms ensures you know what the question is asking. Practice interpreting word problems. Knowing math vocabulary ensures that you understand the questions.
