Helpful, but with multiple mistakes
Do not let your kid go on it by themselves, because 5 to 10% of the time it will tell you the wrong answer is correct or the right answer is wrong, or have some other glitch that can really confuse a kid and causing to do worse on the test.
Example: the question asked “which prefix means ‘not’” and the options were “untie” and “disagree”. Disagree was chosen because it means not agree, but the app said that untie was the correct answer.
I recommend the app, but I’m giving it one star because it requires a parent to be there alongside them, double checking every question, which should not be necessary.
I would not give this one star if the app warned you that someone should double check as the student is doing it.
