I have an SAT in Biology book by Kaplan with practice SATs and
textbook-like information on the biology topics covered. I only
used it for a month. It's nicely wrapped in plastic and only have
some pencil notes and a few highlighted notes in it. The practice
papers have not been written. In 9/10 condition (save the pencil
notes). I bought it for close to S$40 and I'm willing to let it go
for $30 NEGOTIABLE. SMS me at 93373394
