Math (Regular) takes you through GED Math step by step, covering 18 modules from basic to advanced topics. A good fit if you prefer to learn math the traditional way.

Pro Plan Features
Practice Tests with Video Explainers
Each subject includes multiple Video Explainer practice tests, where questions include short video explainers built directly into the question experience. You don’t get scored immediately. Instead, you learn by doing.
This removes test anxiety and lets you focus on understanding.
Instead of just showing a right or wrong answer, these explainers:
- Quickly remind you of the key ideas you need for that question
- Help when the GED mixes different topics together
- Show test-taking strategies like eliminating wrong answers and using the Divide and Conquer approach
Because the explainer appears right where you need it, you learn by doing, without pressure. Read More About

What Makes Onsego Different
Everything Is Included
Our online classes include everything you need to pass all 4 GED tests. You just follow the directions on the screen until you complete each course, including practice tests, and take the test one by one. But there is more to it. Onsego is designed to rebuild your confidence first.
You start with short video lessons. Quick quizzes. And right away, you can see that you’re making progress. You’re getting things right. That feeling of getting it right is what gets the momentum going.
Everything is structured around the actual GED test. You only study what’s on the test. Nothing extra. No filler. And you get practice tests so you know exactly what to expect on test day. Most students spend about an hour a day and feel ready to take the test in around two months.
Confidence That Lasts
Onsego gives you everything you need to pass. The lessons, the practice tests, the structure. But the thing that really counts is something most people overlook: confidence.
When you rebuild your confidence through this process, that doesn’t disappear after test day. You take that with you into a new job, into college, into whatever comes next. That’s what Onsego is really doing for you.
Study Tools and Support
Note-Taking System
A notepad is included in every lesson, so you can take and save notes as you progress through the course. Then, you can download and print these notes to extend your learning outside the Onsego prep course.
Study Planners
Each subject includes two or three study planners to help you stay on track. You can choose from 2-, 4-, or 8-week study plans, depending on how quickly you want to finish.
There is no single right pace. Some students like to move fast, while others prefer to take more time to review lessons, practice more questions, and build confidence before the test. You can also create your own schedule and use our planners for inspiration.
Boosting Confidence and Study Tips
This is a short 5-lesson course that explains how to boost your confidence and study effectively. You will identify your learning style and learn how to change your mindset to achieve what you want. Included in all plans.
Dedicated Support
>Our support team answers your questions 7 days a week. You can reach out to us by phone, chat, or email. We are ready to help you get started and offer support when you need us.
