Awful
This is used for a grade and we take the section assessments but mine automatically took me past the point where I see my results to know if I need to retake it and I only have five attempts or the grade will be a zero and having been on my fourth attempt and told you must complete this test that you didn’t start is very angering you also can’t delete anything once you type it so I missed at least one or two questions due to that overall I hate using the app and hate doing it all together please make it so you don’t automatically be put into another test and make it so we can delete in written answers I will now go cry myself to sleep
Almost forgot you can’t use the website because it prompts you to use the app and you can’t get past that now I will cry myself to sleep

has helped me so much
Math Nation has helped me so much with learning and practicing my math!! I have been using it since middle school and throughout high school and I love it. I can use it to study on the go, and the tutors explain the concepts so well and make it so much easier to understand. my studying has only gotten easier/ more organized and my grades have only improved since i started using math nation!
