This thing is complete garbage and made me very stressed in short words. When I would try and do a math problem just to get it wrong, I'd see the solution or look at an example. They show some steps on how to solve the problem but they don't explain how they got to the point(The pictures will be proof. You'll see it tell you to multiply by -2, wont explain why and then say to multiply by -4 and wont explain why either). But the worse part is that a teacher can give a student a penalty for getting a question wrong! Basically if there are 5 questions to complete. A student gets 3/5 of them but then gets 1 question wrong, if there is a penalty off. Now if the student gets the next question correct they will still be at 3/5 completed questions making them have to get 2 questions correct in a ROW! This is completely unreasonable! So overall, if its to see if your students get what you are teaching them it is not bad nor good but if you want it to help teach them then it's complete garbage, the videos are confusing and the penalties ruin progress if DeltaMath can't even teach how to do the math correctly.
