Developer Response ,

Thank you for your feedback.

A lot of typos

I noticed 6 types within one minute after agreeing to a 3 day trial. For example...”debat” instead of “debate.” The fact that I have already seen this many typos, makes me question if I can trust the test questions and know I’m learning correct information. Also not many questions for each subject.
