The lessons helped me tremendously on my math placement test. I’m attending the University of Alabama this fall. I finished my associates degree in 2016, so I haven’t taken math classes in a long time. After doing the lessons I placed out of the intermediate classes I didn’t want to take, and into calculus. Taking this course has saved me around $2,000 in classes, and my graduation date was moved up. I’d say it was a great investment!

My daughter used to prepare for the Accuplacer math placement test at her university. The school required a score of 279 on the Quantitative Reasoning test to move on to the Accuplacer AAF. The first time, she took it cold and scored a 270, so she was not able to move on to the AAF test. Then she studied on your site and got a 299 on the QR and a 292 on the AAF test, so she is good to go!Your website is very well planned to maximize results while minimizing time investment. The method that worked best for my daughter was to take the practice quiz for each section and then read explanations or watch videos of the problems she missed. That way she wasn't spending time watching videos on topics she already knew/remembered well. I then had her take the full practice tests once she had gone through all of the videos she needed to. Sometimes she didn't even need to view the videos -- your explanations of answers were sufficient in most cases to tell her what she needed to know, but the videos were very helpful when she needed a bit more explanation/step-by-step instruction. Up until this year, she has always done well in math, but a crummy teacher combined with covid virtual school made this year a very tough year for her, and she has lost a lot of confidence as a result. I hope that seeing how well she can do with a bit of good teaching/support has shown her that she can be successful again in this college calculus course.Overall, I was very impressed with how well your website prepared her for the tests, as evidenced by her scores. I will also use your site as she prepares to take the PSAT next year.

I first want to thank you for the MathHelp lessons. They are well done, in a logical order, and I appreciate that they are short, explain the concept with an example (or more), and that there are practice problems in addition to quizzes and tests -- all with the work written out and explained so I could figure out where and why I went wrong in a problem -- and affirm what I did right. It was the best review of math concepts I found while looking for assistance to prep for the ALEKS math placement test at the local community college in which I enrolled. I am 25 years out of grad school (in a social science field), and as I am jumping back into school to pursue nursing -- a heavier math and science field -- I needed to review the concepts that I was able to test out of a few decades ago.I also liked that I could watch the video at double time speed if it was something I just wanted to quickly review :) The examples with word/story problems also helped immensely! I was faced with a couple of them when I took the ALEKS test, and since I had practiced them (their format), they came a lot easier to me. And finally, the fact that there are links to related topics within each lesson made a difference. I checked out a few of the links to related lessons along the way just to make sure I was understanding things as fully as I felt I was, and those lessons reinforced what I knew and gave me confidence to progress to the next section.As for ALEKS, I scored more than what I needed to place into the math class required to complete my prerequisite for the nursing program. I would highly recommend MathHelp!

The ALEKS lessons were indeed very helpful. Your explanations were clear and well laid-out. I’ve been away from math for nearly 30 years now, and I frankly struggled back then when I was learning. Today, I scored an 84 on my ALEKS placement test, which qualifies me for honors math placement within my school. I’d say you guys are doing something right!If I were highlighting a part that was particularly helpful, I’d pick the logarithms. That’s an area that always flummoxed me, but your explanation has turned that weakness into a strength. Simply brilliant.

How do you study for Pre-Algebra?

To study for Pre-Algebra, it is essential to practice after each new lesson. The best approach is to use an online course that provides all of the features listed below.

  1. Video instruction
  2. Background lessons
  3. Guided practice
  4. Printable lesson notes
  5. Printable worksheets for extra problems
  6. Diagnostic quizzes
  7. Interactive tests
  8. Cumulative review
  9. Comprehensive grade reports

What grade level is Pre-Algebra?

Students typically take Pre-Algebra as their 7th or 8th grade math course. However, it might also be offered in 6th grade for those on an advanced track or in 9th grade for students who need more time. Many adults also take the class before attempting college level math.

Why is Pre-Algebra so hard?

The reason the course might seem hard is that it requires algebraic thinking, which is often new for students. Moreover, working with ratios and proportions may be difficult, especially for those who have not mastered fractions. Look for Pre-Algebra help that includes background lessons to build foundational skills and online instruction to guide you along the way.

Is Pre-Algebra harder than Algebra?

Pre-Algebra can seem harder to students because it’s the first time they’re asked to think algebraically. However, Algebra is generally considered to be a harder class because it includes more concepts at a more complex level.

What is taught in Pre-Algebra?

In Pre-Algebra lessons, students are taught the skills necessary to be successful when they move on to Algebra and subsequent math courses. A study guide for this class should include the following concepts.

  • Operations with whole numbers, integers, fractions, and decimals
  • Powers and roots
  • Properties of real numbers and order of operations
  • Ratio, rate, proportion, and percent
  • Algebraic thinking such as patterns, variables, simplifying expressions, and solving equations
  • Geometry concepts including lines, angles, polygons, measurement, area, volume, and the Pythagorean theorem
  • Data representation, basic statistics, and simple probability

Is Pre-Algebra necessary?

Although it may not be necessary for every student to take Pre-Algebra, it provides a solid foundation that’s critical for success in future math classes. It also helps students overcome the initial difficulties they often experience in Algebra.

What should I learn before Pre-Algebra?

Before taking Pre-Algebra, you should have a solid foundation in arithmetic skills as well as familiarity with the skills listed below. A math program covering these concepts will get you ready to pass the course.

  1. Perform operations with whole numbers, fractions, and decimals
  2. Convert between fractions, decimals, and percents
  3. Solve word problems using the four operations
  4. Evaluate numeric expressions with exponents
  5. Compare numbers using inequality symbols
  6. Basic knowledge of geometric shapes and measurement such as perimeter and area
  7. Recognize patterns

What comes after Pre-Algebra?

After Pre-Algebra, which provides the basic skills, students are ready to take high school math. The usual high school sequence is shown below.

  • Algebra 1
  • Geometry
  • Algebra 2
  • Pre-Calculus
  • Calculus (offered in special high school programs)

How do you solve Pre-Algebra problems?

If you’re wondering how to do Pre-Algebra problems, one way is to follow the steps in the examples provided in your textbook. If you have trouble working with a traditional book, an online program that provides guided practice along with audio explanations might be a better approach.

Can you learn Pre-Algebra by yourself?

With enough instruction and practice, you can learn Pre-Algebra by yourself. A curriculum with a teacher inside every lesson, as well as diagnostic quizzes, cumulative review, and interactive tests is a great way to get all the help you’ll need.

How much does a Pre-Algebra tutor cost?

The average cost for a Pre-Algebra tutor is $50 per hour. However, depending on where you live and the qualifications of the instructor, the cost can vary from $25 to $100 per hour. Fortunately, there are also online options that offer the effectiveness of private tutoring at a more affordable price.

What makes Pre-Algebra from MathHelp different?

Unlike other programs, MathHelp was developed by a teacher from one of the top private schools in the country. The instruction and practice are therefore of the highest possible quality. Homeschool families can immediately upgrade their math curriculum to a world-class level, and any parent can provide his or her child with the equivalent of a $20,000-a-year private school education for a tiny fraction of the cost.
