I live in this region and is studying to retake the national test and I need a big amount of tough exercises to practice but I can't find good documents/ textbooks over here. Any appropriate textbooks help me greatly. The topics are: calculus, algebra (especially logarithm), complex numbers, Oxyz algebra(?) (I really don't know what to call this one. It includes the equations of lines, planes, spheres, etc. And vector formulas. No matrices.). Thanks for your help.

What are some good English mathematics exercises textbooks at the level of South East Asia high school programs?
