I am sure that a similar question has been asked before, but I make my ideal textbook and situation more specific.
I would like a textbook on category theory designed for someone who knows basically nothing about category theory. I would also like it to satisfy (as many as possible) of the following
-Accessible (I am learning from scratch and on my own and do not consider myself a "good" student)
-Exercises WITH SOLUTIONS (I know that in the world of university textbooks this is a big ask, hints to some exercises will suffice)
-Relatively short (Please no 600+ page tomes like MacLane. Ideally less than 200 pages.)
Next semester I am enrolled in a subject which uses category theory and this semester I got a really nasty surprise when my lecturer started using category theory despite this not being in the prerequisites for this subject. I wish to somewhat rectify this over the 6 week break between semesters. Since I will be learning on my own, the solutions to exercises is really important. I don't want/need a comprehensive guide to all of category theory, just a book which gives me a decent, accessible grounding.
