When must niet come at the end of the phrase and when must it come sirectly after the verb? I have been told i was wrong for both these placements in this lesson.
Placing niet before the direct object is a form of emphasis and contrast. Here is a link to an explanation of specifically how negation works in Dutch: http://www.dutchgrammar.com/en/?n=WordOrder.45

Why 'herken' with 'ik'? Is it a mistake, or is it a special verb with exceptional conjugation? I was expecting a "ik" ending, like 'Ik herk' or something... Could someone enlight me?
The infinitive is herkennen.
I love how "Ik herken de oranje niet" is an option here. Wij houden van oranje :)
I don't understand where niet goes in sentences. Sometimes it is after the verb, sometimes after the subject, and sometimes at the end. Duolingo is useless for understanding the rules.
