I am overwhelmed with the number of words, phrases, grammar points coming out of the upper, lower, blog, and sights and sounds lessons. I feel like I am trying to swallow an open fire hose of information. I would like more effort on the depth of vacabulary explained, examples of usage, and in the number of examples of the grammar. I suggest a cut back on the volume and increase the depth in each lesson. You will have less overworked employees and listeners.
I believe you could cut back on the number of blog lessons and sights and sounds lessons to give you the resources to do this.
