I was waiting for other ITProTV members to jump in with their wisdom and wit and provide some good experience and guidance for you before I jumped in...but since it was here overnight and no one did. Let me try to offer some help.
We're proud of our success stories with ITProTV. The most success that people have is the combination of using some study guide and to use ITProTV to help provide context or fill in gaps where they felt as if the book didn't cover enough. I can assure you that in our content we cover ever exam objective and subobjective without fail. So the combination of the two is a good combo. We cannot say that just watching videos is enough, but we can say along with your study methods and the ITProTV content your chances of success are really good.
The labs are a sandbox environment right now, They give you ability to test and try to make things work the way you believe they should work. We're working towards lab steps but we've not had time yet to develop them. So that's still in the future. So if you're just new to the field and say, I don't have the time or money to buy equipment and the OSes to try this stuff on it...we'll you have access now to the that environment.
Career-path certification goals should be based on a couple of factors. One is geography. If you live in a larger city where it jobs are highly specialized, you might want to target in a speciality for your career and direct effort towards that goal. If you're in a smaller community, where the "IT guy" is well THE "IT guy", you may instead pursue training and knowledge validation across multiple fields of study and become a better generalist.
The second factor is time and job oriented. If you're shooting for a targeted job or planning for the future. You need to keep that goal in front you at all times and plan out your pursuit of those things.
The best study tips is to try to do anything and everything to learn about what you're trying to do for a new career and make it a hobby. This will increase your desire to pursue, it will add to your knowledge. Try and see if some of these places will give you a tour and talk to guys that you're interested in what they do and what they did to achieve it. Keep your nose to study and learning.
Don't be afraid to get a small part time job or entry level job for the experience and try and see it as how to apply your learning.
Ask questions and post them here...ITProTV members are AWESOME. They'll help you fill in the gaps...they even point out when yours truly leads you astray in his content! ;) So it's a great community that you can get some good feedback from. I'm kinda shocked at how shy everyone has been. :)
