The notebook information appears to be very poorly delineated on this subject. The answers in the micro-quiz seem to fly directly in the face of the BUT BE CAREFUL information given! If the person is selecting SOME of the ORANGES, according to the text the "some" should be alguna since "even if it refers to a plural noun, the pronoun is in the singular form." The lesson dictates appears to need a lot of work.

So this lesson explains that imperfecto can be thought of as currently happening, while the indefinito is something that happened in the past. But then in the lesson that compares the two with "time markers" it says the opposite. Imperfect is meant to indicate something "used to" happen. Seems like a contradiction. Actually the more I try to understand this topic the more it seems like the type of thing I should just try to memorize first, and then try to wrap my head around it much later. 

We do not use vosotros in Colombia, this is really messing up my tests. Is there a way to avoid this? It is just confusing to learn something that is not necessary.

Can I switch the two parts of the sentence and keep the basic structure of each clause and keep the meaning?  For example, instead of "Haciendo unos muebles de madera me corté con la sierra.", could I say:  "Me corté con la sierra haciendo unos muebles de madera."
