Our take

Based on the ratings of 13,510 students, a sample of their written reviews and the syllabus, as the course stood in September 2026. No course pays to be reviewed.

Krista King's algebra course packs Algebra 1 and Algebra 2 into one 16-hour path, with 309 lectures across 18 sections. Each topic has a short video, written notes and a quiz, and the section workbooks add extra problems. It starts at operations and equations and ends at exponential and logarithmic functions. The audience list names current algebra students, homeschool parents and adults coming back to math after years away, and several reviewers fall into that last group.

Reviewers keep returning to the same things: clear explanations, plenty of practice, and a pace that holds attention. One says the course is computational rather than rigorous, which suits self-study and refreshing old knowledge but not anyone chasing proofs. Complaints are few. One person wanted a way to slow the audio, another wanted more assignments, and a low-star reviewer felt the Algebra 2 half read like a textbook. Another had trouble opening lessons on an iPhone. Of roughly 13,500 ratings, about 9,500 are five stars and fewer than 200 are one or two.

The course was last updated in September 2026, and about 84,000 students have enrolled. The lessons are short and each section has quizzes, so it suits small daily sessions. It is a solid pick for anyone who wants one instructor to carry them from basic operations to logarithms, though the Algebra 2 half drew the one sharp criticism.

Best forAdults refreshing school algebra, or students who want Algebra 1 and 2 in one place with lots of quiz practice.
Skip it ifYou want proofs and rigor, or you already know Algebra 1 and only need a few Algebra 2 topics.

Pros

  • Short videos paired with notes and a quiz for each topic, so every lesson has a built-in check
  • Covers Algebra 1 and Algebra 2 in one place, from order of operations to logarithms
  • Reviewers call the explanations clear and to the point, with a pace that holds attention
  • Section workbooks add extra practice problems on top of the quizzes

Cons

  • Computational rather than rigorous, so proofs and deeper theory are not the focus
  • One low-star reviewer says the Algebra 2 half feels like reading from a textbook
  • One reviewer finds the pace a bit fast and wants a way to slow the audio down
The explanations are right to the point and easy to understand. This course is not rigorous in terms of mathematical proofs; it is more computational in nature.
Ricardo Rubio, a student

Listed for all levels, but best for beginners and returners who are comfortable with fractions, decimals and radicals.

Course Description

HOW BECOME AN ALGEBRA MASTER IS SET UP TO MAKE COMPLICATED MATH EASY:

This 418-lesson course includes video and text explanations of everything from Algebra, and it includes 120 quizzes (with solutions!) and an additional 16 workbooks with extra practice problems, to help you test your understanding along the way. Become an Algebra Master is organized into the following sections:

  • Operations and equations

  • Polynomials and factoring

  • Functions and graphing

  • Inequalities

  • Systems of equations

  • Exponents and radicals

  • Ratios and proportions

  • Factoring and rational functions

  • Advanced equations

  • Systems of equations

  • Graphing

  • Manipulating functions

  • Exponential and logarithmic functions



AND HERE'S WHAT YOU GET INSIDE OF EVERY SECTION:

Videos: Watch over my shoulder as I solve problems for every single math issue you’ll encounter in class. We start from the beginning... I explain the problem setup and why I set it up that way, the steps I take and why I take them, how to work through the yucky, fuzzy middle parts, and how to simplify the answer when you get it.

Notes: The notes section of each lesson is where you find the most important things to remember. It’s like Cliff Notes for books, but for math. Everything you need to know to pass your class and nothing you don’t.

Quizzes: When you think you’ve got a good grasp on a topic within a course, you can test your knowledge by taking one of the quizzes. If you pass, great! If not, you can review the videos and notes again or ask for help in the Q&A section.

Workbooks: Want even more practice? When you've finished the section, you can review everything you've learned by working through the bonus workbook. The workbooks include tons of extra practice problems, so they're a great way to solidify what you just learned in that section.

  • "Thank you Krista for making this so clear and understandable! You are a fantastic tutor. A+++" - Omid N.

  • “At the peak of my mathematical skill level I reached only into the very early stages of learning Trigonometry. Fast forward to now (my early 30's) and by experience alone, realize the infinite possibilities of being a master in mathematics. I chose Ms. King's Algebra course as a review to move past my previous level and must say that I not only ENJOY the course she offers but am getting more from it learning wise than I could have imagined. I wish to complete all of her classes and am extremely confident that her teaching style can get me there. Other than mere reference of other resources, I plan to stay on track with all of Ms. King's courses exclusively. Thank you for a great learning experience!” - Dean F.

  • “Great! I love how she teaches!” - Fred B.

By Muthuraman N on 9/11/2026

Very well explained in a simple understandable language. The three quiz questions at the end of each chapter is a great way to reinforce the learning process and to get the feel that we have learnt it thoroughly. Thanks Krista. Looking forward to learning linear algebra and other courses taken by you.

By Don Marc Bänsch on 9/6/2026

Great all-inclusive course for Algebra. As someone who has not been in school for a while but is planning to get a bachelor's degree in a math-adjacent field, this was a great first step to make sure I still had the basics down and close any gaps in my knowledge. I was surprised that I still remembered a lot, though I had completely forgotten some of the most basic concepts. This course gave me the confidence and ability to dive deeper into more complicated math topics.

By Ricardo Rubio on 9/5/2026

Great course! The explanations are right to the point and easy to understand. This course is not rigorous in terms of mathematical proofs; it is more computational in nature. However, if you're self-studying or just refreshing your old knowledge, then this course is a great fit.

By Jana Macklin on 8/3/2026

I really liked Krista King's approach to explaining the various math materials and topics covered in this course. I find both the lecture videos and notes easy to follow and comprehend. This course helped me solidify both Algebra I and Algebra II concepts that I learned back in high school. Definitely worth it.

By Oscar Martijn on 7/28/2026

I am so grateful for having foung this comprehensive course in Algebra 1 and 2 which has proven me that I understood plenty of it already and I had some difficulties grasping some other aspects; definetly has been a theoretical and practical addition to my undestanding of math. Amazing. :)

By Lin Christopher on 5/30/2026

It was pretty good, but I think some further more explanations might be better. For example in the equation, 3x -10 = 8 and the only constants the mentor mentioned was 10 and 8. However, she could've explain why 3x isn't and because 3 was the coefficient of x and not a constant.

By Albert Geluk on 4/18/2026

Great in-depth course, learnt so much. The course is quite long when you do all the Quizzes, which really help to reinforce your understanding. The Resources are very helpful, and can guide you through some of the difficult questions.

By P Munch on 12/30/2025

Definitely a good match. I'm trying to bone up on my Algebra before doing a Review and Clep for College Algebra

By Ronald Haynes on 12/27/2025

I am 67 years old and I haven't touched algebra in 43 years. I wanted to work this part of my brain and so I took a chance and purchased this course. It is far above my expectations. Krista does an excellent job in breaking down everything into small chunks. She has put an amazing amount of work into this. And because of her method it is keeping me moving forward. Thank you.

By Alexander Verner on 11/27/2025

The course covers a large number of topics. In addition to those often covered in such courses, it includes others that are rarely introduced. The theoretical material in the notes is clearly and concisely explained, with detailed examples, while the lectures are made interesting and easy to understand. Mistakes appear here and there, but the staff is working on fixing them. I highly recommend this course.

By Dylan Aaron Hernandez on 11/8/2020

Very well make it

By jerome brandon on 11/8/2020

The instructor is very knowledgeable and offers very good downloadable resources.
