Student Reviews

I should get Onsego prep a long time ago. I was struggling with passing the GED and I wasted so much time trying to piece together free stuff. For a small investment, I got exactly what I needed. Onsego saved me so much time and money and finally, I got my GED.
Onsego made obtaining my GED quick and painless. I was able to get my GED completed in 2 months while on unemployment.
Onsego Prep really did help. I’ve been putting off getting my GED for over 10 years and I now have my GED!
I left high school young to have my daughter and now that she is 3 I have decided to go back and finish so I can make a better life for us. I started on my own but found I couldn’t keep focused. Then I found your course, and I found it very encouraging and am happy to report that passed all 4 tests!
Being able to use Onsego Prep has been a Life Saver! I can log in at any time, and get right to work. It is so easy to use and understand. The quality of learning is exceptional.
Thank you for everything, I passed my GED test after 4 months of joining the course and I am very grateful for your help.
The videos have great explanations with lots of examples that make it easy to understand the problem. This site has helped me a lot since I’ve started using it. Would recommend.
