## 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.

## ACT Math – Pre-Algebra Quiz

Parents – Did you know that the questions on the ACT Math test vary greatly in difficulty? 20 to 25% of the questions are on concepts learned in Junior High while a few very hard questions test concepts students learn in Algebra II and Trigonometry classes

Your child may be thinking that there is no need to study before taking the ACT or worrying that there is too much to review. In reality, preparing for it will increase your child’s score by several points, and CollegeGuide4Parents can help speed up the process.

CollegeGuide4Parents’ Math tools allow students to quickly identify her/his weaknesses and direct them to online educational resources offering a clear explanation of the concepts as well as examples.

If your child takes the 30-question Pre-Algebra quiz on this page, he/she will get a customized report showing the topics she/he should work on. CollegeGuide4Parents’ Pre-Algebra review page list links for will take her/him directly to online providing links to reputable educational websites where she/he will find the information needed.

The easiest Math questions on the ACT represent 20 to 25% of the Math portion of the test.

Your child learned the skills necessary to do well on these questions in Junior High in Pre-Algebra class.

She/He has probably forgotten a lot of what she/he has learned then, but a quick review is most likely all that is necessary for her/him to do well on these questions. The 30-question quiz below will allow your child to quickly identify what she/he needs to focus on.

She/He can also go directly to the review age to go over the main Pre-Algebra skills. If you remember your child struggled in that class, the online worksheets linked from our review page will give her/him the extra practice she/he needs.
