show the 0 and 1 grades first at every schedule review, not after the other grades
It has been a while since I used this app. There are too many carts I've added and one big problem I've been dealing with is that the 0 and 1 grades go to the not-learned carts and I have to answer about 100 carts then I get to them which are more important for me! so I have to give them number 2 to make them come earlier. so please give another algorithm.
