BUS528-SU10 Why I want to study project management

I am Gerald, this is the second semester for me to study in Calmat.
This semester, originally I register four classes, BUS528: Project Management, BUS520: Organizational Behavior, BUS552: Accounting Financial and Managerial, and also Financial. After review all the class, finally I dropped the "Financial" class, because I think I need to spend more time than I expected to each class.
Project Management is highly related to my work. I have worked 15 years in semiconductor industry. I have personally manage several different project. One is called EMU project, which is to design a memory system to support a test equipment. This project requests me to design a memory controller chip, purchase different memory, such as DDR SDRAM, QDR SRAM and other component, design the PCB board and then debug and test. I have about five people under my command. This project really make me exhausted, and it teach me a big lesson. I made many mistakes, and some of them is remendable, some are not. Finally even though we finish this project, but it also cause many regret.
I was also involved in another project, which I am one of the major member of the chip design team. This project is finally also finished, but with a very long delay and high cost.
I wonder if I learn project management before, maybe I can handle my project better.
