Good question and it might have been true in the past but not since we added more than 4 hours of content last year. Specifically, all hormones iterated by the AAMC in their 2009 Official MCAT Guide, are discussed in the necessary detail in our newest edition DVDs.
These 2010 Edition DVDs now also include an MCAT Study Plan, Thermochemistry, Electromagnetism and much more!
Like most courses you will take, all the material is covered in the book (i.e. in this case, the GS MCAT hardcover textbook). Despite these advancements in the videos, you should consider these DVDs in the same way that you would a good course at school: the prof.'s purpose is to make difficult concepts easy to understand, highlight and explain 80-90% of the material, emphasize problem solving techniques to get you ready for the exam, etc.
