Which trainsignal videos for 290?

Unlike cbtnuggets and their single 290 video, trainsignal doesnt have something similar. I see that theyve grouped their mcse videos into three parts but thats a ton of material just for the 290. My employer is willing to buy at least three single videos but Im not sure which ones to get for just 290. Thoughts?

I got a bunch of TestOut's from college a few years back, glad they'll finally go to use.
