Long story short: I have a B. Sc. in EE, and currently doing PhD in Experimental Condensed Matter Physics. I plan to go for industry. I found that it would not be difficult for me to pass the Electrical and Computer PE exam (both the "Computer Engineering" and the "Electrical and Electronics"). 1) Is it worth it for me to do it? It will require some +$400 and some time to study. 2) If the answer to 1) is yes, then which one would be more useful to me to get a job in industry, computer engineering or electronics?
