TXwhere to buy BPP acca p6 mys variant text & kits (until sept 2017)?

Hi, I'm sitting for P6 (MYS) variant paper this coming June. I'm using choong kwai fatt's advanced taxation text book as I couldn't find bpp and kaplan study text for this variant. I would really appreciate it if you can share some guidelines to me on how to prepare for this paper. As I'm self-studying, I'm totally clueless on how to get prepared for it =( Thank you. Best regards, Peggy
