I think the main value of a tutor is having someone with a mental model of what you know and don't know. This has two important consequences. One: If you are missing a prerequisite piece of knowledge the tutor can easily notice that and fix it. If you were on your own it could be a long hunt for the missing piece. And if you misunderstood something, it can take even longer to fix as you don't know that you don't know. Two: The pace can be adjusted so that you practice until you get something, and no longer. Moving at a set pace is frustrating if the pace is too quick, and boring if it is too slow.
