Difference between 看完 and 看到 My homework requires to fill in this blank. 

A: 你看完这本书了没有？
B: 我看。。。一半。


I have 2 options that means "I finish reading half the book".

我看完一半。 

我看到一半。

I am a bit confused because I think 完 involves the entire book. So, both are correct?
Both are correct.

In 我看完一半, the object of 看完 is 一半, so it means I finished reading half of the book.

In 我看到一半, 一半 is used for the position where have been finished reading, so it means I reached half of the book in reading.
