FAQ
Where do the questions and concepts come from?
They are based on the OAR math study materials collected in the Kyle Drive and Gomez Drive. I pulled the recurring concepts and problem types together, then organized them by topic and subtopic.
The questions here practice the same underlying concepts, but they are rewritten with different numbers, wording, or scenarios. The goal is to give you more ways to practice the material, not to replace the original Kyle and Gomez resources.
Did this tool help you prepare for the OAR?
If it did, I would really, really appreciate it if you shared it with someone else who is studying. Tell a friend, mention it in a group, post it on Reddit, or share it anywhere you feel comfortable.
Even something as simple as, “I used this free OAR math study tool and it helped me prepare,” would mean a lot to me. It helps other people find it, and it makes the time I put into building it feel worth it.
