I was talking with a college of mine at Microsoft Ignite here in Atlanta and He said he recommends to his students to check out the Professor Messer website. He has a number of videos for A+, Network+, and Security+ courses. They are all short videos covering the topics in the exams. This looks to be a great resource for your studies. Check it out. http://www.professormesser.com/
