I highly recommend taking a full course with veritas. My instructor, Jennifer Rich, has a complete understanding of the material. I have taken other courses through different prep programs, and with Veritas I saw the greatest score increase. One thing that you will definitely get is an explanation of "why" something works. Too often the explanation of a question stops at just the answer. Throughout my course Jennifer consistently explained why an answer would work. This differentiation allowed me the opportunity to gain an enduring understanding of the material we were covering. Also, taking the full course as opposed to just a self-paced online course is much better. Having to go to class holds you accountable for doing your work and therefore reaching your full potential on test day.
