Are too many books on a subject a boon or a bane?
I am about to appear in a competitive exam in $3$ months for my PhD where one of the topics is complex analysis.
The questions will be of subjective type.
I am trying to learn complex analysis on my own.Though I studied it I am not so strong in it.
In the mean time whenever I am trying to solve the exercises,I am having difficulty in solving them.I am going on downloading books for the exam which will have good exercises.
The more books I am getting,instead of helping me they are making me anxious because there are so many to solve in such a short time.
What should I do now?I am unable to find out that particular book with good exercises that would help me in my exam.
I have bought Gamelin,Bak-Newmann,Shakarchi and Conway,but which should I choose between the three;Neither are helping me to solve the sample questions.Conway and Gamelin are so difficult to solve.Should I get more books?
Please help me what should I do?Where is the problem lying?
