This is FD data for two subjects: Math for 2nd year (midterm and final exams) and Science for 2nd year (midterm and final exams). I purchased it last year. I actually used it for the 1st year midterm and final exams, and it was really helpful. The questions are arranged in order of frequency, so you can study very efficiently. You can also print out only your weak points and use them, making it a truly convenient study material. I don't think there's any other material like this. It's very valuable. Installation itself is very easy; the installation starts automatically when you insert the CD. I think anyone can use it.
