Free Problem Solving Videos

Many of my students simply need to see how I go about solving a problem, and then they become unstuck. I offer these completely free videos to help students get unstuck with their homework or topics they're studying in school. Once you sign up with a free account, you'll have access to:​

  • Over 400 Calculus problem solving questions and solutions.

  • Video explanations on how to solve each type of problem, organized by topic.

  • Unlimited ability to re-watch problems covering the entire range of AP Calculus AB and BC.


Frequently asked questions

How does this compare to Khan Academy or YouTube?

Khan Academy is a great resource for learning the concepts. They do a good job with their explanations. But to actually master problem solving, you need to practice a wide variety of problems, and Khan Academy has only a limited set of problems to practice on. From my experience, students know about and use Khan Academy, but they still prefer the way I explain and setup the problem. YouTube is also a great resource, and I post a lot of great videos on YouTube for AP exam questions and some of the problem solving videos. Again, the problem is a lack of variety of questions to practice. You can try to dig through YouTube to find the specific topic, but some are poor explanations, and they aren't connected to each other. With my videos, you get a consistent view on solving every type of problem and how the concepts are interconnected.

How does it work?

Create an account on the website by clicking on the "Log In" button at the top of any part of this website. Once logged in, you'll have access to the videos on the video pages.

Why do you offer this for free?

Most people can't afford a private tutor, and I can't give away all of my time to help all of those who need it. I want to be able to reach as many students as possible and help them. I want everyone to be able to problem solve regardless of their ability to pay.

How can I support you?

Let me know how the videos have helped you by posting in the forum or sending me an email. I want to see everyone succeed, and sharing your stories of success would really mean a lot to me.

I would also appreciate donations (but definitely not required at all) in order to help me create more content. I have a vision where I'm creating videos from Algebra 1 all the way through advanced math like multi-variable Calculus and Differential Equations, but it will take time to make the videos and put the content up. The more support I get through here, the more time I'm able to devote to creating content for everyone.

Why not put this on YouTube?

YouTube makes it hard for students to engage and ask questions. The comment section for each video can get really messy and disorganized. Instead, I wanted a forum where students can ask questions freely and it's easier for me and other students to see the questions and respond. This is also why you have to have an account, so that you can post questions in the homework help forums. YouTube also has limited features and organization. You mostly can do playlists, but there's no ability to jump to specific questions in a video easily. On my website, I can put a lot of additional functionality to make it easier to use compared to YouTube.

What if I still have questions about a topic or problem?

That's what my homework help forums are for. Once you've created an account, you can post questions in there, and I check them daily and answer students questions. I also have weekly office hours where I'm live and able to take questions and have back-and-forth conversations with students.

What if I have a homework question that isn't covered by the videos?

Post the question in the homework help forum, and I'll answer any questions you have there. If it's a popular enough topic to cover, I'll even add to the existing video solutions.
