I have written the following sentence:
I had taken Course A at School A that is similar to Course B in School B, which appears to be more difficult to get through its prerequisite.
In case the sentence is not making a lot of sense because of the messy references, the idea is: I have taken Course A at School A. I find that Course A is similar to Course B, which is offered by School B. Course B has more difficult prerequisites to get through.
In the sentence, I have a few doubts on the correctness of the references that I have used.
- First, although I have the temptation to use "which" in the first part of the sentence as "...taken Course A at School A, which is similar to...", I wanted to avoid word repetition and used the word "that" in the sentence instead to refer to Course A at School A. Is this correct?
- Second, I always think that "which" refers to its nearest subject and in this case, it is referring to Course B. Is what I have said correct?
- Third, if the word "which" is referring to Course B, can I then assume that using the word "it" within this clause would automatically refer to what "which" refers to, in this case, Course B?
