I am a student self-studying topology. Recently I found Janich's book and its content was wonderful, except that it has no problems.
So I am finding supplementary material that has some challenging exercises that can help me understand the topics.
I don't like a verbose reference-style book. I don't want the book to have too many(more than 30) exercises on a chapter.
For example, baby Rudin would perfectly meet my requirements, but it is not a topology book.
Thanks in advance.
