So after reading endless of Ib related threads I came to the conclusion to buy the Haese&Harris Math HL book. But there is this one problem. I can only find a Book from 2008 with the name Haese&Harris. Here a link: https://www.medimops.de/paul-urban-mathematics-for-the-international-students-ib-dipolma-hl-core-taschenbuch-M01876543116.html Is this the one everyone is talking about and is this book good for a 6-7 points reaching student?
