Questionable answers
I'm enjoying the practice of this app- however, there are definitely some mistakes. Number 23 of pattern folding- the multiple choices had two sets of identical answers. A and D were literally identical as were B and C. #55 for angles is backwards. They ask for angles in increasing order but the correct answer is listed in decreasing order. There have been other mistakes. That is disappointing, but the important thing- that there is practice for thinking spacially this way- is good.
