You're going to need to provide more information if you want some help. What are you struggling with, and what method/s have you tried?
The books I and others here regularly recommend are Stroud and Singh, and if you've read about them in the other threads what additional information are you after?
Stroud can be found in just about any library with a maths section, and they can both be bought at Amazon or other booksellers for about 35 pounds. Either one will cover everything you need for Analytical Methods (and the rest of your HNC/D).
