Chapter 3.2 is much more difficult, much more technical.
Most people took 2 to 3 tries to get a 100%.
Conflating “of” and “to be” were the most common problems. To tell the difference, you have to pay careful attention to which words are mutated.
I’m thinking of breaking this lesson into 2 pieces, have “of” and be in the first half, and “to be” be in the second half. But, I’m not sure if I should do that. Would that make it more difficult to notice the mutation differences?
One comment that seemed to help a lot of people was “turn the possessive phrases into ‘of’ phrases.” I’ll have to find a way to highlight that in the lesson.
