This is the FD data for the mid-term and final exams in social studies. I purchased it new in mid-August of last year. I actually used it for the first semester 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 the weak points and use them, and there really isn't a more convenient study material than this. I don't think there are any other materials like this. It's very valuable. How about it for your future studies or high school entrance exams? 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.
