I took a break from this for a while but kept it because it worked so well now I come back and I don't retain anything because it's not really teaching me anything it's overwhelming with terms that aren't very well explained zoomed through and is another user posted "spoon fed" the answers. I used to be able to retain the info this app gave when learning but now no it just assumes I understand something but doesn't let me actually try to input and learn by actually doing versus them doing it
