A lot of O Levels study guides and 10-years series (past year questions). Many of them are brand new, some with faint pencil marks. Selling at $3 to $10, depending on the original price of book, and condition of book. Definitely less than half the price you have to pay at the bookstore. Meet up at Kovan MRT station.
