Good, But Doesn't Allow Combined Testing Need to allow testing from combined list. Like selecting N5, N4, and N3. Then pull random questions from all 3 levels. Even if you are N3, you must test on N5 and N4 info too. It's annoying to jump between each, allow for combination of levels.
Not helpful This is really bad. Besides the annoying ads the app itself is not useful. It doesn't let you review so you can see what you got wrong or why, and there's no definition to help learn things you don't know. Uninstalling.
Buggy app with only a couple of questions
I dont mind paying for quality app but i hate ad
