Recently Khan Academy has been glitching with the multiple-choice questions in 7th-grade math. It tells me on the bubble that I'm correct but says I'm wrong in line of dots at the bottom right corner.
Probably you're trying to solve a multiple choice question. These questions must be solved choosing ALL answers that apply to get the exercise correct!
Please let me now if is that your problem. If I can help with anything else, please just ask!
