A tutor can give you an opinionated approach to a subject. They can offer you what they believe are the best (well, good) references. They can give you intuitive explanations for why things are true - the kind of explanation that is missing in a typical “rigorous” book. They can tell you what lines make sense to explore at your level and what things you should save wondering about for later. A tutor is another name for a professor, if you expect enough. Studying statistics / ML, I absolutely found that there were “truths” from the text that I would try to prove with simulations and … couldn’t really reproduce. Having somebody tell you that “that chapter is good but those particular statements are controversial / wrong / not exactly saying what you think they are saying” is really valuable. In the end, my opinion is that if you find it easy to learn from a text, probing the boundaries of your understanding could be good. Some stuff is easy. Other stuff just sounds easy but there is a deeper understanding to acquire.
