First, choose according to mathematical ability.
Both SAT and ACT have math tests, and both emphasize algebraic problems, but there are differences between them. The mathematics part of ACT examines a wider range of mathematical concepts, such as logarithm, trigonometric function diagram, matrix, etc., which is not involved in SAT. ACT also has more problems in geometry and trigonometry than SAT.
Moreover, the ACT paper does not provide any mathematical formulas, and you are required to memorize all the mathematical formulas before the exam. The SAT will provide most of the required mathematical formulas on the test paper.
If you are familiar with and good at algebra, you can choose SAT mathematics. If geometry and trigonometry are strong, you can choose ACT mathematics.
Second, according to computing power.
The SAT math score is 800, accounting for half of the perfect score. Mathematics is divided into two parts, one of which is that students are not allowed to use calculators. In contrast, ACT mathematics allows the whole audience to use calculators. If you are used to solving math problems with a calculator, ACT math should be more suitable for you.
Third, according to the familiarity with scientific terms.
ACT needs to examine the science part more than SAT, and charts and graphs are often used in the science part. It will be easier if you know more scientific terms. Scientific research results have a great influence on the comprehensive score of ACT. If you know more about science, the science section can help you improve your total score.
Fourth, according to whether you are good at discovering the details of the article.
Comparing the reading parts of the two exams, we will find that the SAT articles provide more information than the ACT, and usually tell the answer range, and the reading topics and articles are basically in the same order. If you are not good at discovering the details of the article, then SAT reading is easier for you.
Five, according to the type of writing you are good at.
ACT writing focuses on grammar, punctuation and sentence structure; SAT writing pays more attention to writing style and requires higher writing vocabulary. If you have a solid knowledge of grammar, it will be easier to get high marks if you choose ACT.
Sixth, choose according to the speed of doing the questions.
The math part of ACT has a time of 1 minute for each question, and the other parts are less than 1 minute, which requires a higher answering speed than SAT. In terms of time, the ACT test is more tense than the SAT test, but the ACT content is simpler. If you have the ability to do problems quickly, you will gain a greater advantage in the ACT exam.
