mathmatics . . I think "Guidance and Practice" is a better book. It has examples to explain and senior high school entrance examination questions, especially the last question in each lesson, which are all good Olympic math questions. I wonder if you have heard of A Chinese Question. As long as you do all the above questions (Grade One to Grade Three), you can get full marks if there is no problem in the senior high school entrance examination. Now I'm a sophomore, and the effect is not bad with these pamphlets. General English can be tested at around 1 15, and mathematics can be tested at 655438. ! !
