## 7 Quizzes to Improve on the ACT Math Test

Does your child need to improve on the ACT Math test? Does he/she struggle in math? Are you worried a low ACT Math score will negatively affect his/her overall score? A higher result in math could allow him/her to attend a better college. CollegeGuide4Parents is offering free online tools, including 7 quizzes, to help students significantly improve on the ACT Math test.

##### How to improve on the ACT Math test

Students scoring 30 or above on the ACT Math test can, if they dedicate time to practicing, improve their score on their own. Those scoring below 25 on the other hand, often need extra help. Several tutoring programs exist, but most are expensive. Another alternative is to use CollegeGuide4Parents’ free tools. Students making use of them can expect to improve on the ACT Math test by several points.

The ACT Math test consists of 60 questions to be answered in 60 minutes. The level of difficulty varies greatly from one question to the next. Some are on easy concepts taught in Pre-Algebra, while others touch on topics learned in Algebra 2. The way questions are phrased can also increase their level of difficulty.

Some scholars believe that they have a chance to get a better score if they retake the test, even if they have not studied or practiced. In reality, the difficulty level of ACT tests is fairly constant, so without preparing, students will probably not do a lot better the second time around.

To improve on the ACT Math test, students first need to refresh the skills they have learned in Pre-Algebra, Algebra I and Trigonometry classes. Scores between 25 and 30 indicate that a student has forgotten important concepts or formulas. If a student gets lower than 20, it may mean that there are concepts that he/she never fully understood. No need to get discouraged. There are many online resources, including videos, that clearly explain the math concepts necessary to do well on the ACT. CollegeGuide4Parents will direct your student to them.

##### CollegeGuide4Parents’ Online Quizzes

The ACT Math test focuses on concepts of pre-algebra, elementary algebra, intermediate algebra, coordinate geometry, plane geometry and trigonometry. CollegeGuide4Parents created 7 short interactive quizzes designed to help students quickly identify the skills they need to review. When they are done answering a quiz, students are presented with a customized report which shows the mistakes made, the correct answers and the topics they need to work on. They are then directed to a review page which shows a compilation of online resources, they can consult to quickly study the concepts they have difficulties with. Review pages also include links to practice worksheets for those needing to spend extra time on some topics. Finally, the review pages also provide links to ACT problems which the students can work on once they are ready to practice.

Scholars who remember struggling in Algebra II class should not worry. Forty percent of the test is on concepts learned in Pre-Algebra and the easiest part of Algebra I. They can also expect to successfully answer several questions in geometry. In this blog, students will also be able to re-familiarize themselves with trigonometry. They may have had difficulty while taking the class. However, if they check the resources we have prepared, they will realize that once a person knows how to use the Sine, Cosine and Tangent formulas, they can answer most problems.

In conclusion, if your child is having difficulty getting a good ACT Math score, he/she may need to review the concept he/she learned in math class. Studying using CollegeGuide4Parents’ tools will enable him/her to improve on the ACT Math test.
