The more popular questions, such as the ones that appear in lessons, have videos. However, if you are pulling questions from the vast databases of questions, from way back in the 90s, for example, those will not have video explanations. Obviously it would be infeasible to record video explanation for every question ever released, so LSATMax focuses on those questions you are most likely to study. Rule of thumb, if they're in the lessons they will probably have videos, if they are from the depths of our archives probably not.
