I'm pretty confused about the placement of pronouns with infinitves and present participles. It says it is optional to either put it before the verb or attach it to the end of the infinitve or present participle, but in the exercises at the end of the lesson, it considers me “wrong” if I don't do it as they do. Am I missing something? Are there times when tacking it onto the end isn't allowed? If not, why not have both structures on the flash cards and allow both answers in the speaking and writing sections? As it is, I feel unsure about whether I have misunderstood the lesson. Can anyone shed light on this?
(And, if any one who works for Rocket reads these, and it turns out both ways are correct, would you please change the exercises to reflecft that? Thanks.
