I have also noticed that some answers arent correct.
For example, I got a question about carbon dioxide being carried mostly by bicarbonate. I answered true, and it told me it was wrong that carbon MONOXIDE wasnt, but carbon DIOXIDE was.
Responses to the correct answer can be a bit confusing, but overall I would recommend this app. The questions are otherwise on point and you can choose which topic you would like to study. Some of the questions really make you think about what youve learned so thats a plus too.
