It's not anytime soon, but I have to take C++ for Engineers in Spring 2015 eventually.

I would like to have a video tutorial site handy so I can prepare for it.

Any suggestions?

Channel 9 from MSDN, especially series from STL

I don't know about other tutorial sites, but the above are definitely worth watching and are beginner friendly imo. While there, you could check out Going Native 2012 and 2013 videos, the level varies greatly but they're all good to watch.

What about this one? Are these tutorials any good?

It looks ok-ish, but after a cursory look I can say there are a few things I'd do differently (more C++11 features, a better IDE and compiler without a vendor lock-in, actually using algorithms instead of reinventing the wheel). But if it works for you, I think you won't learn anything terribly wrong from there.

You should look into a safari books subscription. They have thousands of books and video compilations. Ex. Full C++ Deitel brothers book in video lectures etc... I used this site while working through my CS degree and it was amazingly helpful.

If you don't want to pay for a sub then you might look up thenewboston , Projecteuler or simply surf YouTube for the MIT course ware lectures related to computer science.
