agree with the above posters. now I have problems sticking to a schedule at times so I really like DIT. plus I am more of an auditory learner, so if thats your style I would say check it out. I also like how they expand on some of the topics in first aid, but if you are motivated you could probably do it on your own. also there may or may not be ways to see some of the 2012 videos to see if you would want to buy the 2013 version (or just use the old videos and possibly score a copy of the workbook).
