People are sensitive. Common words that are used to describe people have suddenly been given a new, underlying meaning of 'you are lesser'. Oftentimes it's not the word itself, but the tone in which it's said. Take 'minor' for example. A minor would perceive that label as offensive if you said it to debunk his/her argument. A minor would engage in a conversation of being unable to drive with the reasoning - "I'm not old enough yet." You could see words as positive or negative only when someone comes along and uses it. Fat used to be adjective, but somehow in today's day and age - or when you got older - it's now a dirty word.
So when you say someone is handicapped, according to today's logic, you're telling them they're imperfect. And that's a bad thing.
Use of subordinate clauses is more of a grammatical thing, and if the writer is not sure if a sentence is correct he/she may ask a peer reviewer to edit or comment on it. However, the body of the essay is a standard for every essay assigned and it should be much easier for the writer to tell if he/she is following the rules.
The first step was to plan out how and when you wanted to study. Then, you had to physically get together and talk about the topic you were studying, like by taking notes and reading articles. Then you needed to assess all of your group's notes and study them, too. Then, when the test or quiz came, you would be more prepared whereas if you didn't study at all.
