TITLE: Topology exercises
QUESTION [23 upvotes]: Can anyone suggest a collection of (solved) exercises in topology? Undergrad level, as a companion to Dugundji's Topology (although excellent it doesn't provide the solutions to the problems).
Thanks.

O. Ya. Viro, O. A. Ivanov,
N. Yu. Netsvetaev, V. M. Kharlamov, is available freely online at 

http://www.pdmi.ras.ru/~olegviro/topoman/eng-book-nopfs.pdf

This book is published by AMS and that comes with solutions.

REPLY [7 votes]: "Fundamentals of General Topology: Problems and Exercises" by A. V. Arkhangel'skii; V.I. Ponomarev is a fun book, though it might be hard to find and the level might be higher than you'd like.

REPLY [6 votes]: I'd recommend "Elementary Topology Problem Textbook" by Viro, Ivanov, Netsvetaev, Kharlamov.
