The intel graphics and nvidia are separate but cannot be run together. The intel chip is integrated onto the CPU and cannot run anything more than videos and very basic games. The 950m is the only one that will be doing the work in games. It will run BF1, this link shows you will have about 45 fps at medium graphics: click here.
As for other options we could probably recommend lots of varieties, ultimately it would probably be best for you to read reviews and give us options to compare. I think the one you are looking at looks like a good start though and should do what you need it to. The only thing I would look at if you're going to uni is battery life; you don't want it dying on you after an hour.
