While I accept that the repetition is pretty annoying, it does help drive each point home.

However I do have to agree with Emma that iodine would turn something brown/black not blue.

The repetition is very annoying.. it would be better a bit shorter as 3 quizzes with 20 questions in each as going through 85 questions most of which are repeated 3 times) is rather tedious

the repetition was a bit annoying but it did show me what i new and the repetition helped me learn the answers easier. i do agree with everybody else that iodine does black/brown when it comes into contact with starch not blue!!!! ;-)
