And how does that work, in the cases that I don't notice the problem in
the proof? Of course, it is expected that at some point in one's
education that won't happen, but until then I would like to be more
sure of my answers.

I will let other people explain how getting the answers to Jacobson's
algebra, or Rudin's analysis, won't help you become able to solve the
problems on your own.

Nothing helps just by existing, it's usefulness depends on how it's
used. For me, the solutions are used to check my own solutions. In
fact, to be sure, it doesn't even have to be for a book in print or
with exercises that are used in any exam today. But it needs to be a
classic book.

If the situation is such that there is embargo to the student body for
understandible reasons (such as in secondary school) then it's just the
same for me to first do the problem set, and then send them to somene
who has the official solutions, and then have sent to me the official
solutions. When comparing, I see when a different proof technique is
used, details I fill are left out or vice versa, etc and in this way my
ability increases.
