This is FD data for one year of science for the first grade, covering mid-term and final exams. I purchased it new last summer, so the data is almost up-to-date. I actually used it for mid-term and final exams, and it was really helpful. The questions are arranged in order of frequency of appearance, so you can study very efficiently. You can also print out only your weak points and use them, and there really isn't a study aid as convenient as this. I don't think there are any other materials like this. It's very valuable. I think you can use it for summer vacation study, or for advance study for the second semester. Installation itself is very easy; the installation starts automatically when you insert the CD. I think anyone can use it. I will also include the enclosed instruction manual.
