I tried studying on my own for about two months during the winter, but I just couldn't understand it and felt lost. I finally had some time to take this course, and it was so great because all the concepts I didn't know were cleared up at once. Also, the problem-solving methods were concise and well-structured enough to solve them without any hitches in a real exam setting. Thanks to this, I passed after listening to the lectures for just one week. Due to time constraints, I listened to the lectures for 4 days + spent about 2 days going through the practice problems (163 questions) twice, reviewed the ones I got wrong again, and looked at about 200 questions from the front and 50 from the back of the dump. Although I felt the actual exam was slightly harder than the problems I solved here, I was able to solve everything using the concepts taught in this course. Thanks to you, I passed with a score of 749 and am leaving this review!
