You are the first curriculum reform in Guangxi. Don't buy a five-year simulation of the three-year college entrance examination. If you are too famous, you must have seen those problems. I recommend you to use three-dimensional design and test research. Tian Li's 38 sets are not simulation questions, but real questions. You are going to prepare for senior three. No matter whether you can't write Tian Li's mathematics in arts and sciences now, science can't write Tian Li's comprehensive management at all. If you don't review to that extent, you will have a poor foundation before buying review materials.
