Query: Great reference book

I'm taking the Investments course within the Certified Financial Planner program. This book really helped clarify many of the terms and formulas we had to learn. The Mayo text covers the material, but from a more academic slant. I just wish I had bought the Feibel book well before the class started. It may not be technical enough for graduate students in Finance or people who normally read scholarly papers on investment theory. But for everyone else, like individual investors or people going back to school learning investing fundmentals, it's a great reference.
