Well I chose the obvious ones for an ace investigator- Computer Science, Medicine/Physiology, Photiography and Engineering- Electrical. Any others will kind of be there maybe hobbies or things she picked up. Although once I had an hit woman type that was a damned good wifey sort with Home Economics and Crafts. Remember odd skills can be used creatively and some are useful like Physical Education (swimming, jumping and other obvious stunts).
