I am so glad I found your program - it helped me so much. I've been out of school for over 20 years and I recently enrolled in the Kansas State dietetics program. I was freaking out over the algebra placement exam because I couldn't remember anything. After completing your program, I scored a 34 (I only needed a 21 to get into college algebra). So, thank you for your great program, I couldn't have done it without you 😃

I am a 50+ who decided to go back to school late in life. I need to take College Algebra to obtain my degree. To avoid prerequisite math classes, I needed to pass their placement test.It has been a “a few years” since I took a math class. I needed to study and searched for online courses. I came across many sites, but Mathhelp.com had the best setup, so I signed up. The course covers everything you will need to know. I went through the entire course and took the final exam a few times as reinforcement.The courses are put together in an easy-to-follow manner and provide everything you will need to pass any math test. The layout was easy to follow. The video, followed by practice, followed by the questions were so easy to follow. It is all on one page. There is no navigating back and forth. If you get one wrong, you are given a step-by-step explanation on how to get the correct answer. The reinforcement of each concept is helpful. The videos really make it so easy to learn. The three instructors are great and teach each subject clearly and in a detailed manner.Whether your child is struggling in elementary school, or you are a college student who needs some extra help, Mathhelp.com is the solution to your needs.I aced my placement test. I now feel fully prepared for the College Algebra class I'm taking next semester. I highly recommend this course.

My College Algebra course went well thanks to your program. The most helpful elements to me were the multiple videos of explanations that started off extremely basic and built up difficulty. I do not learn very well when I get blasted in the face with information then an overly difficult problem. Also the practice tests helped with learning and then performing which helped me retain the lesson.

I was attempting to place into calculus I and I did achieve that. I scored an 85 on the ALEKS. I was a very poor student in high school just so you understand the full picture. I'm trying to catch up on things I should have had a basic foundation in back then. So it was really nice to have a refresher course on all the rules and properties of math and algebra leading up to the calculus portions. Overall, I think the material was very well put together on your site. Clear and concise.

As a math-phobe, I needed as much help on the FTCE math test as could get. A teacher at my school suggested your program. I loved your back-to-basics approach to help someone like me, a 58-year-old who never liked or could do math. I found your instructions and lots of practice questions and tests to be extremely helpful. I took many of the questions over and over again to get the steps correct. I always especially had trouble with measurements and geometry, and I think your program helped ease my anxiety and confront those questions head on. It also helped me get straight in my head the positives/negatives and when they apply in addition, multiplication, etc., as well as how to take a word problem and make it into a solvable algebra equation. It was an extremely helpful program for me. Keep up the great work!

That course was the absolute reason in my success of the TSIA2 test. I did pass it and can take College level algebra instead of developmental math. Specifically speaking, the quadratic equations, functions/graphing, linear equations in two variables and expressions, equations and formulas really helped. So I'd most definitely give that course a lot of credit to helping me pass.

The Accuplacer Elementary Algebra exam went really well. I was able to place into my appropriate college algebra class, and I surprised myself with my score even. I had not been in school for years and the courses on MathHelp made jumping back in so much easier. There were so many helpful elements of the course. The instructional videos and the practice exam were instrumental in helping me.

I passed my college algebra course with an A, thanks to your online course! The explanation in the videos were very detailed and easy to understand; the quizzes really drove the information home into my mind. It felt good going into a quiz and being confident in knowing how to do the problem, with time to spare to check my work, then seeing high marks in my grade book after.I am an adult student, (working and going to school) coming back to college algebra from a long time away from school! I really needed a refresher.It is a vast improvement in my understanding of math (I was not too great with math in general in elementary and high school). Thank you for giving me a boost in "mathematical confidence"! Thank you so much!

Thank you so much for this algebra course!!! I am enrolled in an online college degree program at Penn Foster College. I am a Graphic Design major, but they stuck me in an algebra class. I do NOT have a mind for math, I barely made it through math in school. So this class has been devastating for me, my entire degree depends on this one class! I have never had algebra in my entire life and they put me in Intermediate Algebra right off the bat! Oh, did I mention that they do not actually teach the classes they offer, they send you the text book, and you are literally on your own. Your classes are a lifesaver! I thought I was looking at Chinese, but your step by step lessons actually made sense. If it weren't for you I would have flunked out a long time ago, and lost any chance to get the degree that I have worked so hard on. You are providing a much needed service, THANK YOU SO MUCH!!!

Let me start off by saying how fantastic this website is. During Algebra in 9th grade, I was struggling and needed extra help. When distance learning started due to the pandemic, I was even more stressed and I needed help somewhere, this is when I found mathhelp.com. I tried the free trial and within an hour, I was highly impressed. I could go to the lesson my teacher was teaching and get extra help which was amazing and I was caught up until school ended. From there, I wanted to do even more math so I used this site the entire summer and I am taking the second half of Algebra this year. With all the work I put in over the summer, Algebra is now a breeze and I am so far ahead and am currently doing the geometry course too! This site is amazing, the presenters explain stuff very well and there's no room for confusion in my opinion.

I loved this program. I didn’t do Math in 13 years so I subscribed to MathHelp two months before I started my Intermediate Algebra class. I was ahead of the lessons and I would always come back to MathHelp as my primary source for understanding a topic.. explanation was clear, the teachers were awesome, my favourite was the gentleman.. he thought so clearly that I understood and then I made sure to practice and practice and practice. I received a B+ in my Intermediate Math Course

I found the College Algebra course to be EXTREMELY helpful. I thought every concept was explained in a way that was easy for me to understand. I am currently enrolled in a College Algebra course at a university after spending over 15 years out of school. I tried to take the same course in spring of 2019 and was completely lost because I didn't remember any of the fundamental concepts. I feel like the course on your website has adequately prepared me for this semester and I expect to have success. Thank you for providing these resources for students such as myself. There's no way that I could feel as confident going into this semester without having gone through the training that you provided. Thank you for all that you and your team does. I wish you all the best.

I'm a 40 year old going back to college at Penn State online to finish my business degree. I have not taken a math class in 20 years and when I found out that I had to take the Aleks test, I researched tutorials online. Out of the many tutorials that I sampled before I purchased, mathhelp.com was the best at providing short lessons that were to the point. I finally understand Algebra because of these lessons. I took the Aleks test this week and scored high enough to place me into Algebra II.After Algebra II, my only other math class will be Calculus. That was my goal and I accomplished it. I do plan on using mathhelp.com again when I start Algebra II in the spring semester and also when I take Calculus. Because of this tutorial, I am no longer terrified of math!

Mathhelp.com was extremely helpful. I increased my math placement test score by 135 points by using the website. I am now ready to take college algebra. The teachings are a good pace and the most helpful thing are the links to previous lessons that remind you of building blocks you need for the current lesson. Also, the option to have the audio of a problem on the practice problems is extremely helpful.

Wanted to say thanks so much for putting together the Mathhelp curriculum for people like me. Without all the content I would not have been successful on the TSI placement test. The most helpful was definitely the factoring, exponent rules and fractions involving radicals since you see a lot of that on the test. Overall it was very easy to learn and follow and built my confidence up and helped me be successful. I scored a 350 out of a possible 390 according to my advisor and now I’m in my second week of college algebra on a summer mini semester! Thanks to all of you and keep up the good work. I made a suggestion to my school that they should recommend your site to people like me as a prep for the placement test.

## How can I improve my Geometry skills?

As with any math course, time spent practicing is the best way to improve Geometry skills. The best websites for learning Geometry will include practice problems with complete audio explanations along with printable extra problems and notes. The most important skills to develop are listed below.

• Master processes from Algebra, such as simplifying and evaluating expressions, writing and solving linear equations, and graphing
• Recognize basic shapes and understand their properties
• Enhance memorization abilities
• Improve logical thinking
• Increase attention to detail

## What is taught in high school Geometry?

High school Geometry lessons focus on size, shape, position, and dimension. (The name of the course literally means “earth measure.”) The following is a list of concepts typically included in the curriculum.

1. Points, lines, planes, and space
2. Line segments, rays, and angles
3. Parallel and perpendicular lines
4. Triangles, quadrilaterals, and other polygons
5. Congruence and similarity
6. Right triangles and trigonometry
7. Circles and their properties
8. Three-dimensional figures
9. Measurement, area, surface area, and volume
10. Reasoning, proofs, and logical thinking

## What grade is Geometry taught in high school?

Geometry is usually taught in 10th grade. It can also be taught in 9th grade, but only if the students have already
taken Algebra 1.

## Can I take Geometry online?

Yes, you can successfully take a Geometry class online. However, you’ll need a stand-alone course with all of the features listed below.

• A teacher inside every example and practice problem
• Guided practice to build skills
• Printable worksheets for independent and extra practice
• Printable notes to highlight and annotate
• Diagnostic quizzes to identify strengths and weaknesses
• Background lessons to build foundational skills
• Cumulative reviews to reinforce and retain prior learning
• Interactive tests and grade reports for immediate feedback

## How do you pass Geometry?

If you’re wondering how to pass Geometry, the most important thing to know is that each new concept builds on the previous one, so you can’t afford to fall behind. The best online Geometry help will have background lessons built into each new concept to make sure you’re always up to speed.

## Is Geometry hard to learn?

High school Geometry can be hard to learn because it represents a new way of thinking about math. Students must apply logical and spatial reasoning in addition to problem solving skills in order to understand the lessons.

## Why do students struggle with Geometry?

Some of the reasons that students struggle with Geometry are listed below.

1. They can’t remember the background Algebra concepts that are often required.
2. They aren’t familiar with the properties of basic shapes and have trouble visualizing a problem-solving strategy.
3. They haven’t taken the time to memorize the vocabulary necessary to answer the questions correctly.

## Is Geometry easier than Algebra?

Whether or not Geometry is easier depends on the individual student. For some students, it’s easier because they like the visual aspect of working with shapes, and there’s often more than one way to solve a problem. Other students find Algebra easier, however, because it involves a procedure for solving problems and has more in common with other math courses.

## How do you study for Geometry?

The best way to study is to do your Geometry homework assignments neatly on paper. Because it’s such a visual course, it’s a big help when you can see your work clearly and you organize it well. A great way to learn how to show your work is to use an online Geometry tutor in the form of a video instructor who presents all the steps in the examples and provides guided practice as well.

## How much does a Geometry tutor cost?

The average cost of a Geometry tutor ranges from \$35 to \$50 per hour. However, depending on your situation and the expertise of the instructor, the hourly cost can be as high as \$100. If you’re seeking an affordable alternative to hiring a high school Geometry tutor, an online program that features one-on-one instruction may be just the ticket.

## How do you solve Geometry problems easily?

Students in need of Geometry homework help can use the following steps to solve problems more easily.

• Study and label the given figure or draw one of your own.
• List the information given and identify any that is unnecessary.
• Note what you are asked to find and identify related definitions, theorems, and postulates.
• Look at similar example solutions and set up a method or an equation to be used.
• State your solution and check the results.

## Can I skip Geometry and go to Algebra 2?

Because concepts from high school Geometry lessons can be helpful when solving Algebra 2 problems, it would not be a good idea to skip the course. If you do go straight from Algebra 1 to Algebra 2, however, you must then take Geometry. In other words, you can’t skip the course entirely – it’s too important.

## Is Geometry useful in real life?

Geometry is very useful in the real world and in everyday life. In addition to being found in nature, it’s used for measuring, building, art, and design. The importance of studying this course is demonstrated by the many jobs that require its use. Some examples are listed below.

• Architect
• Computer Graphics and Video Game Design
• Mechanical Engineer
• Robotics
• Medical Imaging
• Surveyor
• Construction
• Manufacturing
• Cartographer
• Astronomy

## What makes Geometry 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.
