Guess work is VERY important, only when you are NOT talking to your teacher! A good guess work keeps conversation flow and the satisfaction you feel is priceless.
But when you are talking to your teacher in a class, it's better to understand every word there is. That is the education part in the word "educated guess". Random guss is not as good as educated one. Only after you chewed, analyzed, and digested all the words, sentences with your teacherduring a meaningful conversation, you can produce really good guess work when you are outside of a classroom.
