The Berkeley Review MCAT books in Thomson Hill, Northeast Singapore for sale

Hi, I have a set of Berkeley Review MCAT books for sale, except for the Verbal Reasoning book. I bought them off Amazon (very good to almost new condition) in June 2013. Don't believe there has been a newer edition yet. I did not get much use out of them as I gained admission to a physiotherapy course shortly after and decided to go for that instead, so the internal condition remains very good to almost new just as I purchased them. I did, however, accidentally spilled soup on the table where I placed them long time ago; it seeped to where the books were so there are some reddish stains on the covers of a few of them (you can see them in the pictures).
The Biology part I and II, as well as General Chemistry part I do not have the original cover but a printed one; I'm not sure if the previous owner re-bound the book or photocopied the entire book then bound it, but I've cross-checked with a friend's books before and the contents are as per the original book.
Selling each set at S$45, pick-up and cash only. Thanks!
