ACT exam

Introduction to the test subjects

English:

• Content: In the form of 5 passages, underline sentences throughout the original text and set options in corresponding places to ask students to choose whether to keep or modify. It is a grammatical error correction and semantic coherence correction based on texts.
• Difficulty analysis: When Chinese students are exposed to English since childhood, their fixed thinking is to translate directly, that is, at the semantic level. This part of the test needs to consider the grammatical level (parts of speech, sentence structure, English conventions and usage norms, etc.) first, and then consider the semantic and pragmatic aspects on the premise of ensuring that they are correct.

Mathematics:

• Content: Complete 60 multiple-choice questions in 60 minutes, and the knowledge points examined include:

  (1) Arithmetic (Pre-Algebra) such as: numbers, absolute values, one-time equations, probabilities, etc.;

  (2) Elementary algebra such as: variables, algebraic expressions, quadratic equations, solving, applying exponents and square roots, etc.;

  (3) There are also some intermediate algebras, such as: the understanding and application of quadratic equations, the expression of roots and rational numbers, inequalities and absolute value equations, sequences, quadratic inequalities, functions, matrices, the roots of polynomials, etc.;

  (4) Geometric coordinates, such as: points, lines, polynomials, circles, curves, parallels, perpendiculars, distances, midpoints, transformations, quadratic curves, etc. in the standard x,y coordinate plane;

  (5) Plane geometry such as: the properties and relations of plane figures, including angles, rectangles, parallelograms, trapezoids, circles, parallel lines, orthogonal lines, translation, rotation, perimeter, area, volume, etc.;

  (6) Trigonometry, such as: the investigation of right triangles, trigonometric functions, values, properties and graphs, trigonometric identities, etc.

• Difficulty analysis:ACT math is one of the easy to get high scores and perfect scores, but most students cannot guarantee high scores or full scores for various reasons, which will be very regrettable. There are some of the main difficulties and reasons for not getting a high score and a perfect score:

  (1) Due to the wide scope of investigation, students have not learned some knowledge points, such as the multiplication of matrices, the division of complex numbers, and the properties of standard normal distributions.

  (2) There are also topics that have been learned but have a vague or incomplete understanding of the knowledge points, such as the equations of circles and ellipses in geometry, the relevant properties, and the factor of polynomials.

  (3) In addition, due to the lack of understanding of some words, the speed of doing questions is slow and wrong, such as congruent, hypotenuse, etc.

Read:

• Examination content: 3 single articles and 1 double article are required to be completed within 35 minutes, a total of 4 articles, and the order of their genres is fixed, which are novels, social sciences, humanities, and natural sciences. The types of questions examined involve vocabulary, details, elimination, inference, purpose, writing perspective, attitude, theme of the text, chronological ordering, seeking similarity, seeking differences, interconnection, etc.
• Difficulty analysis:There are two major difficulties in ACT reading:

  1. Students are required to read an article of about 1000 words and complete 10 questions within 8.5.

  2. There are many novel articles, and it is difficult for students to understand; Even if the students have read it, they only have a general impression when answering the questions, and they cannot quickly find the positioning sentences, and the accuracy rate is not high.

Science:

• Investigation content:At the heart of the ACT Science section is the scientific method and scientific thinking, which covers a wide range of disciplines. This section assumes basic scientific knowledge and focuses on students' understanding of textual and graphic information. Upon completion of this course, students will be able to acquire "Basic Science Knowledge", "Ability to Understand Data Charts", "Ability to Understand Science Experiments", "Ability to Extract Key Points from Complex Textual Information", "Ability to Understand Opinions, Reasoning and Evidence", and "Ability to Handle Different Types of Texts Efficiently".
• Difficulty analysis:The text and graphic information of ACT science is complex, and it is necessary to have the ability to understand the requirements of the question in a short period of time, and extract effective content from the complicated text and graphic information for reasoning. This reasoning ability is not divided into arts and sciences, but it will be a challenge for students who usually don't read much charts. In addition, there are indeed a small number of topics in ACT science that require students to master the knowledge of physics, chemistry and biology that they have learned in the nine-year compulsory education period. In this regard, students may not learn well or have forgotten this knowledge, and they need to check and fill in the gaps.

Writing (optional):

• Examination content: In 40 minutes, write an argumentative essay that reflects a certain depth of thinking on a current topic that a high school student has a certain cognition of, such as life challenges, AI technology, animal medical anatomy, etc.
• Difficulty analysis: Students need to demonstrate a certain degree of critical thinking ability, the ability to develop and argue in multiple dimensions for the topic, the ability to lay out the whole article and plan the paragraphs, and the ability to express the style and words consistently.
