The private lessons at DDM were very useful and efficient for me. I started my lessons one year before SAT, and I organized my schedule, duration, and frequency of the lessons with my teacher according to my program. I also chose the subjects of our lessons according to my deficiencies. It was helpful to have one-to-one courses because of these advantages. I recommend DDM if you want to have a stress-free process of self preparation for SAT.
